+# Conductor C# SDK Improvement Plan
+
+## Making C# SDK on par with the Python SDK
+
+### Context
+
+The Python SDK (conductor-python) is the gold-standard reference implementation with 33+ examples, 12 high-level clients, 44 task types, full telemetry, event system, comprehensive testing, and rich documentation. The C# SDK has a solid foundation (16 API clients, 20+ task types, AI orchestration, worker framework) but has significant gaps. This plan addresses every gap systematically.
+
+---
+
+## GAP ANALYSIS: What's Missing in C#
+
+### A. CRITICAL BUGS TO FIX FIRST (5 bugs)
+
+| # | Bug | File | Issue |
+|---|-----|------|-------|
+| 1 | Namespace typo | `Conductor/Definition/TaskType/LlmTasks/LlmIndexText.cs:18` | `Conductor.DefinitaskNametion.TaskType.LlmTasks` should be `Conductor.Definition.TaskType.LlmTasks` |
+| 2 | Duplicate key in LlmChatComplete | `Conductor/Definition/TaskType/LlmTasks/LlmChatComplete.cs:173` | `WithInput(Constants.MAXTOKENS, StopWords)` should be `WithInput(Constants.STOPWORDS, StopWords)` |
+| 3 | Inverted cancellation check | `Conductor/Client/Worker/WorkflowTaskExecutor.cs:254` | `if (token == CancellationToken.None)` should be `if (token != CancellationToken.None)` |
+| 4 | Stack trace destroyed | `Conductor/Client/Worker/WorkflowTaskService.cs:50` | `throw ex;` should be `throw;` |
+| 5 | Interface typo | `Conductor/Client/Interfaces/IWorkflowTaskCoodinator.cs` | `IWorkflowTaskCoodinator` should be `IWorkflowTaskCoordinator` (missing 'r') |

+6. **NuGet package**: `dotnet pack` produces valid package
+7. **API compatibility**: Existing public APIs remain backward-compatible (no breaking changes)
+
+---
+
+## ESTIMATED TOTAL EFFORT
+
+| Phase | Estimate |
+|-------|----------|
+| Phase 1: Bug Fixes & Code Quality | 1-2 days |
+| Phase 2: High-Level Client Layer | 3-5 days |
+| Phase 3: Missing Task Types | 2-3 days |
+| Phase 4: Worker Framework | 3-4 days |
+| Phase 5: Metrics & Telemetry | 2-3 days |
+| Phase 6: Event System | 2-3 days |
+| Phase 7: AI/LLM Providers | 1-2 days |
+| Phase 8: Examples | 3-5 days |
+| Phase 9: Testing | 3-5 days |
+| Phase 10: Documentation | 2-3 days |
+| **Total** | **~22-37 days** |
+
+---
+
+## OPEN QUESTIONS FOR TEAM REVIEW
+
+1. **Metrics library**: Should we use `System.Diagnostics.Metrics` (built-in .NET) or `prometheus-net` (community standard)? Python uses Prometheus directly.
+2. **Testing framework**: xUnit is already in the project. Should we use Moq or NSubstitute for mocking?
+3. **Phase prioritization**: Are there phases the team wants to reorder or defer? E.g., skip Event System (Phase 6) if not customer-requested?
+4. **Breaking changes**: The interface typo fix (Bug #5: `IWorkflowTaskCoodinator` -> `IWorkflowTaskCoordinator`) is technically a breaking change. Ship it in a major version bump, or accept the break?
+5. **Min .NET version**: Currently targets .NET 6+. Should we require .NET 8+ to leverage newer APIs (e.g., `System.Diagnostics.Metrics` improvements)?
+6. **NuGet versioning**: What version should the improved SDK ship as? Current is likely 1.x - does this warrant a 2.0?

Subject: [PATCH 03/19] Add high-level client layer with 9 interfaces and Orkes
 implementations

Interfaces: IWorkflowClient, ITaskClient, IMetadataClient, ISchedulerClient,
ISecretClient, IAuthorizationClient, IPromptClient, IIntegrationClient,
IEventClient - each wrapping the raw API clients with cleaner APIs.

Orkes implementations delegate to the underlying auto-generated API clients.
OrkesClients factory creates all clients from a single Configuration.

Void-returning async API methods are wrapped with Task.Run() to provide
proper Task-based async signatures on the high-level interfaces.

Subject: [PATCH 05/19] Add worker framework improvements: exponential backoff,
 health checks, lease extension, pause/resume

- Adaptive exponential backoff on empty poll queues (configurable multiplier and max interval)
- Worker health check tracking (consecutive errors, task counts, timestamps)
- IsHealthy() and GetHealthStatuses() on coordinator for monitoring
- Lease extension timer for long-running tasks (> configurable threshold)
- Runtime pause/resume via environment variable checking
- New configuration options in WorkflowTaskExecutorConfiguration

Subject: [PATCH 06/19] Add metrics and telemetry infrastructure using
 System.Diagnostics.Metrics

Provides counters and histograms for:
- Task polling (count, success, empty, error, latency)
- Task execution (count, success, error, latency)
- Task updates (count, error, retry, latency)
- Worker restarts and payload sizes
- API calls (count, error, latency)
Includes TimingScope helper for latency measurement.
Integrates with OpenTelemetry and Prometheus exporters.

Subject: [PATCH 07/19] Add event system with listener interfaces and
 thread-safe dispatcher

- ITaskRunnerEventListener: poll, execution, and update lifecycle events
- IWorkflowEventListener: workflow start, complete, fail, terminate, pause, resume events
- EventDispatcher: singleton with thread-safe listener registration and dispatch
- Safe exception handling in dispatch to prevent listener errors from affecting workers

Subject: [PATCH 09/19] Add comprehensive unit tests for all SDK improvements
 (106 tests)

Test coverage for:
- Phase 1: Bug fix regression tests (namespace, stopwords key, cancellation, stacktrace, interface name)
- Phase 2: OrkesClients factory and client interface tests
- Phase 3: All 13 new task type DSL tests (HttpPoll, Kafka, StartWorkflow, Inline, LLM tasks, MCP, Tool)
- Phase 4: Worker monitor health checks, executor configuration defaults
- Phase 5: Metrics counters, histograms, timing scope, MeterListener integration
- Phase 6: Event dispatcher registration, unregistration, multi-listener, error isolation
- Phase 7: AI provider enums, config classes for all 9 new providers + 2 vector DBs

All 106 tests pass.

Subject: [PATCH 10/19] Complete Phase 4-6 gaps: auto-restart, 3-tier config,
 WorkerMetrics, async dispatch

Phase 4: Auto-restart with configurable max retries and delay, 3-tier
configuration (code < global env vars < worker-specific env vars)
Phase 5: MetricsConfig for toggling metric categories, WorkerMetrics
per-worker helper with consistent tagging and timing scopes
Phase 6: Async event dispatch methods (DispatchTaskRunnerEventAsync,
DispatchWorkflowEventAsync)

Subject: [PATCH 12/19] Add comprehensive test suite: 195 unit tests across 12
 test files

New test files:
- SerializationTests: 30 tests for model JSON round-trip (WorkflowDef,
  TaskDef, WorkflowTask, Task, TaskResult, StartWorkflowRequest,
  Workflow, WorkflowStatus, SubWorkflowParams, TaskMock, WorkflowTestRequest)
- HighLevelClientTests: 25 tests for mocked client interfaces
  (IWorkflowClient, ITaskClient, IMetadataClient, ISchedulerClient,
  ISecretClient, IPromptClient, IAuthorizationClient)
- WorkerFrameworkTests: 20 tests for worker config edge cases
  (exponential backoff, auto-restart, lease extension, pause/resume,
  3-tier config, health status)
- WorkflowBuilderTests: 31 tests for ConductorWorkflow builder and
  all task type DSLs (Simple, HTTP, HttpPoll, Switch, ForkJoin,
  DoWhile/Loop, SubWorkflow, Wait, Terminate, Inline, JQ, Kafka,
  StartWorkflow, LLM tasks, MCP tasks)

Subject: [PATCH 13/19] Rewrite documentation: README, workers, workflows,
 config, metrics

- README.md: comprehensive rewrite with quick-start, features overview,
  task types table, AI/LLM section, examples table, documentation links
- workers.md: expanded with all worker features (auto-discovery, annotated
  workers, health checks, event listeners, metrics)
- workflow.md: expanded with all task types, workflow operations,
  workflow testing, AI/LLM workflows, RAG pipeline, MCP agent
- worker_configuration.md: new guide covering exponential backoff,
  auto-restart, lease extension, pause/resume, 3-tier config, health checks
- metrics.md: new guide covering all metrics, WorkerMetrics helper,
  MetricsConfig, MeterListener, OpenTelemetry/Prometheus integration

+### 2. Configure the client
 
-   
-### Setup Conductor C# Package​
+```csharp
+using Conductor.Client;
+using Conductor.Client.Orkes;
 
-```shell
-dotnet add package conductor-csharp
+var configuration = new Configuration
+{
+    BasePath = "http://localhost:8080/api",
+    AuthenticationSettings = new OrkesAuthenticationSettings("keyId", "keySecret")
+};
+
+var clients = new OrkesClients(configuration);
+```
+
+### 3. Create a worker
+
+```csharp
+using Conductor.Client.Interfaces;
+using Conductor.Client.Models;
+using Conductor.Client.Worker;
+
+public class GreetWorker : IWorkflowTask
+{
+    public string TaskType => "greet";
+    public WorkflowTaskExecutorConfiguration WorkerSettings { get; } = new();
+
+    public TaskResult Execute(Task task)
+    {
+        var name = task.InputData.GetValueOrDefault("name", "World");
+        task.OutputData["greeting"] = $"Hello, {name}!";
+        return task.Completed();
+    }
+}
 ```
 
-## Configurations
+### 4. Define a workflow
+
+```csharp
+using Conductor.Definition;
+using Conductor.Definition.TaskType;
+using Conductor.Executor;
+
+var workflow = new ConductorWorkflow()
+    .WithName("greet_workflow")
+    .WithVersion(1)
+    .WithTask(new SimpleTask("greet", "greet_ref")
+        .WithInput("name", "${workflow.input.name}"));
 
-### Authentication Settings (Optional)
-Configure the authentication settings if your Conductor server requires authentication.
-* keyId: Key for authentication.
-* keySecret: Secret for the key.
+var executor = new WorkflowExecutor(configuration);
+executor.RegisterWorkflow(workflow, overwrite: true);
+```
+
+### 5. Start workers and run
 
 ```csharp
-authenticationSettings: new OrkesAuthenticationSettings(
-    KeyId: "key",
-    KeySecret: "secret"
-)
+using Conductor.Client.Worker;
+
+var host = WorkflowTaskHost.CreateWorkerHost(configuration, new GreetWorker());
+await host.StartAsync();
+
+var workflowId = executor.StartWorkflow(workflow);
+Console.WriteLine($"Started workflow: {workflowId}");
 ```
 
-### Access Control Setup
-See [Access Control](https://orkes.io/content/docs/getting-started/concepts/access-control) for more details on role-based access control with Conductor and generating API keys for your environment.
+## Features
+
+### High-Level Client Layer
+
+The SDK provides high-level client interfaces for all Conductor APIs:
 
-### Configure API Client
 ```csharp
-using Conductor.Api;
-using Conductor.Client;
-using Conductor.Client.Authentication;
+var clients = new OrkesClients(configuration);
 
-var configuration = new Configuration() {
-    BasePath = basePath,
-    AuthenticationSettings = new OrkesAuthenticationSettings("keyId", "keySecret")
+IWorkflowClient workflowClient = clients.GetWorkflowClient();
+ITaskClient taskClient = clients.GetTaskClient();
+IMetadataClient metadataClient = clients.GetMetadataClient();
+ISchedulerClient schedulerClient = clients.GetSchedulerClient();
+ISecretClient secretClient = clients.GetSecretClient();
+IAuthorizationClient authClient = clients.GetAuthorizationClient();
+IPromptClient promptClient = clients.GetPromptClient();
+IIntegrationClient integrationClient = clients.GetIntegrationClient();
+IEventClient eventClient = clients.GetEventClient();
+```
+

+- **Metrics** collection via `System.Diagnostics.Metrics`
+
+See [Worker Configuration Guide](docs/readme/worker_configuration.md) for details.
+
+### Metrics & Telemetry
+
+The SDK collects metrics using `System.Diagnostics.Metrics`:
+
+```csharp
+using Conductor.Client.Telemetry;
+
+// Per-worker metrics
+var workerMetrics = new WorkerMetrics("my_task", "worker-1");
+workerMetrics.RecordPoll(success: true, taskCount: 3);
+workerMetrics.RecordExecution(success: true);
+
+// Listen for metrics
+using var listener = new MeterListener();
+listener.InstrumentPublished = (instrument, meterListener) =>
+{
+    if (instrument.Meter.Name == ConductorMetrics.MeterName)
+        meterListener.EnableMeasurementEvents(instrument);
 };
+```
+
+See [Metrics Guide](docs/readme/metrics.md) for the full reference.
 
-var workflowClient = configuration.GetClient<WorkflowResourceApi>();
+### Event System
 
-workflowClient.StartWorkflow(
-    name: "test-sdk-csharp-workflow",
-    body: new Dictionary<string, object>(),
-    version: 1
-)
+Monitor worker and workflow lifecycle events:
+
+```csharp
+using Conductor.Client.Events;
+
+var dispatcher = EventDispatcher.Instance;
+dispatcher.Register(new MyTaskRunnerListener());
+dispatcher.Register(new MyWorkflowListener());
+```
+
+### Workflow Testing
+
+Test workflows without executing real tasks using `TaskMock`:
+
+```csharp
+var testRequest = new WorkflowTestRequest(
+    name: "my_workflow",
+    version: 1,
+    taskRefToMockOutput: new Dictionary<string, List<TaskMock>>
+    {
+        { "task_ref", new List<TaskMock>
+            {
+                new TaskMock(status: TaskMock.StatusEnum.COMPLETED,
+                    output: new Dictionary<string, object> { { "result", "mocked" } })
+            }
+        }
+    },
+    workflowDef: workflow
+);
+
+var result = workflowClient.TestWorkflow(testRequest);
 ```

+# Metrics Guide
+
+## Overview
+
+The Conductor C# SDK collects metrics using the `System.Diagnostics.Metrics` API, making them compatible with any .NET metrics exporter (Prometheus, OpenTelemetry, Azure Monitor, etc.).
+
+## Meter Name
+
+All metrics are published under the meter name: `Conductor.Client`
+
+```csharp
+using Conductor.Client.Telemetry;
+
+// Access the meter name
+string meterName = ConductorMetrics.MeterName; // "Conductor.Client"
+```
+
+## Available Metrics
+
+### Counters
+
+| Name | Type | Tags | Description |
+|------|------|------|-------------|
+| `conductor.task.poll.count` | Counter<long> | taskType, workerId | Polls performed |
+| `conductor.task.execution.count` | Counter<long> | taskType, workerId, status | Tasks executed |
+| `conductor.task.update.count` | Counter<long> | taskType, workerId, status | Task updates sent |
+| `conductor.api.call.count` | Counter<long> | endpoint, status | API calls made |
+| `conductor.worker.restart.count` | Counter<long> | taskType, workerId | Worker restarts |
+
+### Histograms
+
+| Name | Type | Tags | Description |
+|------|------|------|-------------|
+| `conductor.task.poll.latency` | Histogram<double> | taskType | Poll latency (ms) |
+| `conductor.task.execution.latency` | Histogram<double> | taskType | Execution time (ms) |
+| `conductor.task.update.latency` | Histogram<double> | taskType | Update latency (ms) |
+| `conductor.api.latency` | Histogram<double> | endpoint | API call latency (ms) |
+| `conductor.task.payload.size` | Histogram<double> | taskType, direction | Payload size (bytes) |
+
+## Using WorkerMetrics
+
+The `WorkerMetrics` class provides a convenient per-worker metrics helper:
+
+```csharp
+using Conductor.Client.Telemetry;
+
+var metrics = new WorkerMetrics("my_task_type", "worker-1");
+
+// Record a poll
+metrics.RecordPoll(success: true, taskCount: 3);
+metrics.RecordPollLatency(15.5);
+
+// Record execution with timing
+using (metrics.TimeExecution())
+{
+    // ... do work ...
+}
+metrics.RecordExecution(success: true);
+
+// Record task update
+metrics.RecordUpdate(success: true);
+metrics.RecordUpdateLatency(5.2);
+
+// Record payload size
+metrics.RecordPayloadSize(2048);
+```
+
+## MetricsConfig
+
+Control which metric categories are collected:
+
+```csharp
+var config = new MetricsConfig
+{
+    Enabled = true,
+    TaskPollingMetricsEnabled = true,
+    TaskExecutionMetricsEnabled = true,
+    TaskUpdateMetricsEnabled = false,    // Disable update metrics
+    PayloadSizeMetricsEnabled = true
+};
+
+var metrics = new WorkerMetrics("my_task", "worker-1", config);
+```
+
+## Timing Scopes
+
+Use `ConductorMetrics.Time()` for automatic latency recording:
+
+```csharp
+using (ConductorMetrics.Time(ConductorMetrics.ApiLatency,
+    new KeyValuePair<string, object>("endpoint", "/api/tasks/poll")))
+{
+    // ... API call ...
+}
+```
+
+## Consuming Metrics
+
+### Using MeterListener (Built-in .NET)
+
+```csharp
+using System.Diagnostics.Metrics;
+
+using var listener = new MeterListener();
+
+listener.InstrumentPublished = (instrument, meterListener) =>
+{
+    if (instrument.Meter.Name == ConductorMetrics.MeterName)
+    {
+        meterListener.EnableMeasurementEvents(instrument);
+    }
+};
+
+listener.SetMeasurementEventCallback<long>((instrument, measurement, tags, state) =>
+{
+    Console.WriteLine($"Counter: {instrument.Name} = {measurement}");
+});
+
+listener.SetMeasurementEventCallback<double>((instrument, measurement, tags, state) =>
+{
+    Console.WriteLine($"Histogram: {instrument.Name} = {measurement:F2}");
+});
+
+listener.Start();
+```
+
+### Using OpenTelemetry
+
+```csharp
+// Install: dotnet add package OpenTelemetry.Exporter.Prometheus.AspNetCore
+builder.Services.AddOpenTelemetry()
+    .WithMetrics(metrics =>
+    {
+        metrics.AddMeter(ConductorMetrics.MeterName);
+        metrics.AddPrometheusExporter();
+    });
+```
+
+### Using Prometheus (prometheus-net)
+
+```csharp
+// Install: dotnet add package prometheus-net
+// The System.Diagnostics.Metrics are automatically bridged
+// by prometheus-net when using the .NET metrics listener
+```
+
+## Direct Metric Access
+
+For advanced use cases, access the metric instruments directly:
+
+```csharp
+// Counters
+ConductorMetrics.TaskPollCount.Add(1,
+    new KeyValuePair<string, object>("taskType", "my_task"));
+
+ConductorMetrics.TaskExecutionCount.Add(1,
+    new KeyValuePair<string, object>("taskType", "my_task"),
+    new KeyValuePair<string, object>("status", "success"));
+
+// Histograms
+ConductorMetrics.TaskExecutionLatency.Record(42.5,
+    new KeyValuePair<string, object>("taskType", "my_task"));
+
+ConductorMetrics.TaskPayloadSize.Record(1024,
+    new KeyValuePair<string, object>("taskType", "my_task"),
+    new KeyValuePair<string, object>("direction", "input"));
+```

+# Worker Configuration Guide
+
+## Overview
+
+The C# SDK provides a comprehensive worker framework with configurable polling, error handling, health checks, and metrics. This guide covers all configuration options.
+
+## Basic Worker Configuration
+
+Every worker implements `IWorkflowTask` and can configure its behavior via `WorkflowTaskExecutorConfiguration`:
+
+```csharp
+public class MyWorker : IWorkflowTask
+{
+    public string TaskType => "my_task";
+    public WorkflowTaskExecutorConfiguration WorkerSettings { get; }
+
+    public MyWorker()
+    {
+        WorkerSettings = new WorkflowTaskExecutorConfiguration
+        {
+            BatchSize = 5,
+            PollInterval = TimeSpan.FromMilliseconds(100),
+            Domain = "my-domain"
+        };
+    }
+
+    public TaskResult Execute(Task task)
+    {
+        // Worker logic
+        return task.Completed();
+    }
+}
+```
+
+## Configuration Properties
+
+| Property | Default | Description |
+|----------|---------|-------------|
+| `BatchSize` | 1 | Number of tasks to poll in each batch |
+| `PollInterval` | 100ms | Interval between poll requests |
+| `Domain` | null | Task domain for routing |
+| `MaxPollBackoffInterval` | 10s | Maximum backoff when queue is empty |
+| `PollBackoffMultiplier` | 2.0 | Multiplier for exponential backoff |
+| `MaxConsecutiveErrors` | 10 | Max errors before marking unhealthy |
+| `MaxRestartAttempts` | 3 | Max auto-restart attempts on failure |
+| `RestartDelay` | 5s | Delay between restart attempts |
+| `LeaseExtensionEnabled` | false | Enable lease extension for long tasks |
+| `LeaseExtensionThreshold` | 30s | Time threshold to trigger extension |
+| `PauseEnvironmentVariable` | null | Env var name to pause worker |
+| `PauseCheckInterval` | 5s | How often to check pause state |
+
+## Exponential Backoff
+
+When a poll returns no tasks, the worker automatically backs off to reduce server load:
+
+```csharp
+WorkerSettings = new WorkflowTaskExecutorConfiguration
+{
+    PollInterval = TimeSpan.FromMilliseconds(100),         // Initial interval
+    MaxPollBackoffInterval = TimeSpan.FromSeconds(10),     // Max backoff
+    PollBackoffMultiplier = 2.0                            // Double each time
+};
+```
+
+The backoff sequence: 100ms → 200ms → 400ms → 800ms → 1.6s → 3.2s → 6.4s → 10s (capped).
+On successful poll, the interval resets to the base value.
+
+## Auto-Restart
+
+Workers automatically restart on unhandled exceptions:
+
+```csharp
+WorkerSettings = new WorkflowTaskExecutorConfiguration
+{
+    MaxRestartAttempts = 5,
+    RestartDelay = TimeSpan.FromSeconds(10)
+};
+```
+
+After `MaxRestartAttempts` consecutive failures, the worker stops and is marked unhealthy.
+
+## Lease Extension
+
+For long-running tasks, enable lease extension to prevent timeouts:
+
+```csharp
+WorkerSettings = new WorkflowTaskExecutorConfiguration
+{
+    LeaseExtensionEnabled = true,
+    LeaseExtensionThreshold = TimeSpan.FromSeconds(60) // Extend if task runs > 60s
+};
+```
+
+## Pause/Resume via Environment Variables
+
+Workers can be paused at runtime without restarting:
+
+```csharp
+WorkerSettings = new WorkflowTaskExecutorConfiguration
+{
+    PauseEnvironmentVariable = "CONDUCTOR_WORKER_PAUSED",
+    PauseCheckInterval = TimeSpan.FromSeconds(5)
+};
+```
+
+Set the environment variable to `"true"` to pause, remove or set to `"false"` to resume.
+
+## 3-Tier Configuration
+
+Configuration is applied in layers (later layers override earlier ones):
+
+1. **Code** — Values set in `WorkflowTaskExecutorConfiguration`
+2. **Global environment** — `CONDUCTOR_WORKER_*` variables
+3. **Worker-specific environment** — `CONDUCTOR_WORKER_{taskType}_*` variables
+
+```csharp
+var config = new WorkflowTaskExecutorConfiguration();
+
+// Apply global overrides from environment
+config.ApplyEnvironmentOverrides();
+
+// Apply task-specific overrides
+config.ApplyEnvironmentOverrides("my_task_type");
+```
+
+### Environment Variables
+
+| Variable | Config Property |
+|----------|----------------|
+| `CONDUCTOR_WORKER_POLL_INTERVAL` | PollInterval (ms) |
+| `CONDUCTOR_WORKER_BATCH_SIZE` | BatchSize |
+| `CONDUCTOR_WORKER_DOMAIN` | Domain |
+
+Prefix with task type for worker-specific overrides:
+- `CONDUCTOR_WORKER_my_task_POLL_INTERVAL=5000`
+- `CONDUCTOR_WORKER_my_task_BATCH_SIZE=10`
+
+## Health Checks
+
+Monitor worker health status:
+
+```csharp
+var coordinator = /* get from WorkflowTaskHost */;
+
+// Check overall health
+bool healthy = coordinator.IsHealthy();
+
+// Get per-worker status
+var statuses = coordinator.GetHealthStatuses();
+foreach (var status in statuses)
+{
+    Console.WriteLine($"Worker: {status.Key}");
+    Console.WriteLine($"  Healthy: {status.Value.IsHealthy}");
+    Console.WriteLine($"  Running Workers: {status.Value.RunningWorkers}");
+    Console.WriteLine($"  Total Tasks: {status.Value.TotalTasksProcessed}");
+    Console.WriteLine($"  Errors: {status.Value.TotalTaskErrors}");
+    Console.WriteLine($"  Last Poll: {status.Value.LastPollTime}");
+}
+```
+
+## Worker Host
+
+The `WorkflowTaskHost` manages the lifecycle of all workers:
+
+```csharp
+var host = WorkflowTaskHost.CreateWorkerHost(
+    configuration,
+    new GreetWorker(),
+    new ProcessWorker(),
+    new NotifyWorker()
+);
+
+await host.StartAsync();
+
+// Graceful shutdown
+await host.StopAsync();
+```
+
+## ASP.NET Core Integration
+
+Register workers as a background service:
+
+```csharp
+// In Program.cs
+builder.Services.AddSingleton<Configuration>(sp => new Configuration
+{
+    BasePath = "http://conductor:8080/api"
+});
+
+builder.Services.AddHostedService<ConductorWorkerService>();
+
+// BackgroundService implementation
+public class ConductorWorkerService : BackgroundService
+{
+    private readonly WorkflowTaskHost _host;
+
+    public ConductorWorkerService(Configuration config)
+    {
+        _host = WorkflowTaskHost.CreateWorkerHost(config, new MyWorker());
+    }
+
+    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
+    {
+        await _host.StartAsync(stoppingToken);
+    }
+}
+```

 # Writing Workers with the C# SDK
 
-A worker is responsible for executing a task. 
-Operator and System tasks are handled by the Conductor server, while user defined tasks needs to have a worker created that awaits the work to be scheduled by the server for it to be executed.
+## Overview
 
-Worker framework provides features such as polling threads, metrics and server communication.
+A worker is responsible for executing a task. Operator and system tasks are handled by the Conductor server, while user-defined tasks need a worker that polls the server for work.
 
-### Design Principles for Workers
-Each worker embodies design pattern and follows certain basic principles:
+The worker framework provides polling, metrics, error handling, health checks, and server communication.
 
-1. Workers are stateless and do not implement a workflow specific logic. 
-2. Each worker executes a very specific task and produces well-defined output given specific inputs. 
-3. Workers are meant to be idempotent (or should handle cases where the task that partially executed gets rescheduled due to timeouts etc.)
-4. Workers do not implement the logic to handle retries etc, that is taken care by the Conductor server.
+## Design Principles
 
-### Creating Task Workers
-Example worker
+1. Workers are **stateless** and do not implement workflow-specific logic
+2. Each worker executes a **specific task** and produces well-defined output given specific inputs
+3. Workers should be **idempotent** (handle cases where a partially executed task gets rescheduled)
+4. Workers do not implement retry logic — that is handled by the Conductor server
+
+## Creating a Worker
+
+Implement the `IWorkflowTask` interface:
 
 ```csharp
-public class SimpleWorker : IWorkflowTask
+using Conductor.Client.Interfaces;
+using Conductor.Client.Models;
+using Conductor.Client.Worker;
+
+public class GreetWorker : IWorkflowTask
 {
-    public string TaskType { get; }
+    public string TaskType => "greet";
+    public WorkflowTaskExecutorConfiguration WorkerSettings { get; } = new();
+
+    public TaskResult Execute(Task task)
+    {
+        var name = task.InputData.GetValueOrDefault("name", "World");
+        task.OutputData["greeting"] = $"Hello, {name}!";
+        return task.Completed();
+    }
+}
+```
+
+### Task Result Status
+
+Return the appropriate status from your worker:
+
+```csharp
+// Success
+return task.Completed();
+
+// Failure (will retry based on task definition)
+return task.Failed("Something went wrong");
+
+// Failure with terminal error (no retry)
+return task.FailedWithTerminalError("Unrecoverable error");
+
+// In progress (task will be polled again later)
+return task.InProgress("Still processing...");
+```
+
+## Starting Workers
+
+Use `WorkflowTaskHost` to manage worker lifecycle:
+
+```csharp
+using Conductor.Client;
+using Conductor.Client.Worker;
+
+var configuration = new Configuration
+{
+    BasePath = "http://localhost:8080/api"
+};
+
+var host = WorkflowTaskHost.CreateWorkerHost(
+    configuration,
+    new GreetWorker(),
+    new ProcessWorker(),
+    new NotifyWorker()
+);
+
+await host.StartAsync();
+```
+
+## Configuring Workers
+
+Each worker can customize its behavior:
+
+```csharp
+public class BatchWorker : IWorkflowTask
+{
+    public string TaskType => "batch_task";
     public WorkflowTaskExecutorConfiguration WorkerSettings { get; }
 
-    public SimpleWorker(string taskType = "test-sdk-csharp-task")
+    public BatchWorker()
     {
-        TaskType = taskType;
-        WorkerSettings = new WorkflowTaskExecutorConfiguration();
+        WorkerSettings = new WorkflowTaskExecutorConfiguration
+        {
+            BatchSize = 10,                                          // Poll 10 tasks at once
+            PollInterval = TimeSpan.FromMilliseconds(500),          // Poll every 500ms
+            Domain = "production",                                   // Task domain
+            MaxPollBackoffInterval = TimeSpan.FromSeconds(30),      // Max backoff on empty queue
+            PollBackoffMultiplier = 2.0,                             // Exponential backoff multiplier
+            MaxRestartAttempts = 5,                                  // Auto-restart on failure
+            RestartDelay = TimeSpan.FromSeconds(10),                // Delay between restarts
+            LeaseExtensionEnabled = true,                            // Extend lease for long tasks
+            LeaseExtensionThreshold = TimeSpan.FromSeconds(60),     // Extend if > 60s
+        };
     }
 
-    public TaskResult Execute(Task task)
+    public TaskResult Execute(Task task) => task.Completed();
+}
+```
+
+See [Worker Configuration Guide](worker_configuration.md) for full details.
+
+## Worker Auto-Discovery
+
+Discover workers by scanning assemblies:
+
+```csharp
+using System.Reflection;
+
+var assembly = Assembly.GetExecutingAssembly();
+var workerTypes = assembly.GetTypes()
+    .Where(t => typeof(IWorkflowTask).IsAssignableFrom(t) && !t.IsInterface && !t.IsAbstract)
+    .ToList();
+
+foreach (var type in workerTypes)
+{
+    var worker = (IWorkflowTask)Activator.CreateInstance(type);
+    Console.WriteLine($"Found worker: {worker.TaskType}");
+}
+```
+
+## Annotated Workers
+
+Use attributes for simpler worker definitions:
+
+```csharp
+public class AnnotatedWorkers
+{
+    [WorkerTask("send_email", 5, "default", 200)]
+    public static TaskResult SendEmail(Task task)
     {
+        // Send email logic
         return task.Completed();
     }
 }
 ```
 
-## Starting Workers
-You can use `WorkflowTaskHost` to create a worker host, it requires a configuration object and then you can add your workers.
+## Metrics
+
+The worker framework collects metrics automatically:
+
+| Metric | Description |
+|--------|-------------|
+| `conductor.task.poll.count` | Polls performed per task type |
+| `conductor.task.poll.latency` | Time to poll for tasks |
+| `conductor.task.execution.count` | Tasks executed (success/failure) |
+| `conductor.task.execution.latency` | Task execution time |
+| `conductor.task.update.count` | Task status updates sent |
+| `conductor.task.update.latency` | Time to update task status |
+| `conductor.task.payload.size` | Input/output payload sizes |
+
+See [Metrics Guide](metrics.md) for configuration and export options.
+
+## Health Checks
+
+Monitor worker health at runtime:
 
 ```csharp
-using Conductor.Client.Worker;
-using System;
-using System.Threading.Thread;
+// Check if all workers are healthy
+bool allHealthy = coordinator.IsHealthy();
 
-var host = WorkflowTaskHost.CreateWorkerHost(configuration, new SimpleWorker());
-await host.startAsync();
-Thread.Sleep(TimeSpan.FromSeconds(100));
+// Get per-worker health details
+var statuses = coordinator.GetHealthStatuses();
 ```
 
-Check out our [integration tests](https://github.com/conductor-sdk/conductor-csharp/blob/92c7580156a89322717c94aeaea9e5201fe577eb/Tests/Worker/WorkerTests.cs#L37) for more examples
+## Event Listeners
+
+Monitor worker events for logging, alerting, or custom metrics:
 
-Worker SDK collects the following metrics:
+```csharp
+using Conductor.Client.Events;
 
+public class MyTaskListener : ITaskRunnerEventListener
+{
+    public void OnPolling(string taskType, string workerId, string domain) { }
+    public void OnPollSuccess(string taskType, string workerId, List<Task> tasks) { }
+    public void OnPollEmpty(string taskType, string workerId) { }
+    public void OnPollError(string taskType, string workerId, Exception ex) { }
+    public void OnTaskExecutionStarted(string taskType, Task task) { }
+    public void OnTaskExecutionCompleted(string taskType, Task task, TaskResult result) { }
+    public void OnTaskExecutionFailed(string taskType, Task task, Exception ex) { }
+    public void OnTaskUpdateSent(string taskType, TaskResult result) { }
+    public void OnTaskUpdateFailed(string taskType, TaskResult result, Exception ex) { }
+}
 
-| Name               | Purpose                                      | Tags                             |
-| ------------------ | :------------------------------------------- | -------------------------------- |
-| task_poll_error    | Client error when polling for a task queue   | taskType, includeRetries, status |
-| task_execute_error | Execution error                              | taskType                         |
-| task_update_error  | Task status cannot be updated back to server | taskType                         |
-| task_poll_counter  | Incremented each time polling is done        | taskType                         |
-| task_poll_time     | Time to poll for a batch of tasks            | taskType                         |
-| task_execute_time  | Time to execute a task                       | taskType                         |
-| task_result_size   | Records output payload size of a task        | taskType                         |
+EventDispatcher.Instance.Register(new MyTaskListener());
+```
 
-Metrics on client side supplements the one collected from server in identifying the network as well as client side issues.

 # Authoring Workflows with the C# SDK
 
-## A simple two-step workflow
+## Overview
+
+The C# SDK provides a fluent builder API for defining workflows as code. Workflows are composed of tasks that execute in sequence, in parallel, or conditionally.
+
+## A Simple Workflow
 
 ```csharp
 using Conductor.Client;
 using Conductor.Definition;
+using Conductor.Definition.TaskType;
 using Conductor.Executor;
 
-ConductorWorkflow GetConductorWorkflow()
+var workflow = new ConductorWorkflow()
+    .WithName("my_first_workflow")
+    .WithVersion(1)
+    .WithDescription("A simple two-step workflow")
+    .WithTask(new SimpleTask("fetch_data", "fetch_ref")
+        .WithInput("url", "${workflow.input.url}"))
+    .WithTask(new SimpleTask("process_data", "process_ref")
+        .WithInput("data", "${fetch_ref.output.result}"));
+
+var configuration = new Configuration { BasePath = "http://localhost:8080/api" };
+var executor = new WorkflowExecutor(configuration);
+
+// Register the workflow
+executor.RegisterWorkflow(workflow, overwrite: true);
+
+// Start the workflow
+var workflowId = executor.StartWorkflow(workflow);
+Console.WriteLine($"Started workflow: {workflowId}");
+```
+
+## Task Types
+
+### Simple Task (Worker)
+
+```csharp
+var task = new SimpleTask("task_name", "task_ref")
+    .WithInput("key1", "value1")
+    .WithInput("key2", "${workflow.input.param}");
+```
+
+### HTTP Task
+
+```csharp
+var httpTask = new HttpTask("http_ref", new HttpTaskSettings
 {
-    return new ConductorWorkflow()
-        .WithName("my_first_workflow")
-        .WithVersion(1)
-        .WithOwner("developers@orkes.io")
-            .WithTask(new SimpleTask("simple_task_2", "simple_task_1"))
-            .WithTask(new SimpleTask("simple_task_1", "simple_task_2"));
-}
-
-var configuration = new Configuration();
-
-var conductorWorkflow = GetConductorWorkflow();
-var workflowExecutor = new WorkflowExecutor(configuration);
-workflowExecutor.RegisterWorkflow(
-    workflow: conductorWorkflow
-    overwrite: true
+    uri = "https://api.example.com/data",
+    method = "GET"
+});
+```
+
+### HTTP Poll Task
+
+```csharp
+var pollTask = new HttpPollTask("poll_ref", new HttpTaskSettings
+{
+    uri = "https://api.example.com/status/${workflow.input.jobId}"
+});
+```
+
+### Inline Task (JavaScript)
+
+```csharp
+var inlineTask = new InlineTask("inline_ref",
+    "function e() { return $.input_val * 2; } e();");
+inlineTask.WithInput("input_val", "${workflow.input.number}");
+```
+
+### JSON JQ Transform
+
+```csharp
+var jqTask = new JQTask("jq_ref", ".data | map(select(.active)) | length")
+    .WithInput("data", "${fetch_ref.output.response.body}");
+```
+
+### Switch (Decision)
+
+```csharp
+var switchTask = new SwitchTask("switch_ref", "${workflow.input.action}");
+
+switchTask.WithDecisionCase("approve",
+    new SimpleTask("approve_task", "approve_ref"));
+
+switchTask.WithDecisionCase("reject",
+    new SimpleTask("reject_task", "reject_ref"));
+
+// Default case
+switchTask.WithDefaultCase(
+    new SimpleTask("default_task", "default_ref"));
+```
+
+### Fork/Join (Parallel)
+
+```csharp
+var sendEmail = new SimpleTask("send_email", "email_ref");
+var sendSms = new SimpleTask("send_sms", "sms_ref");
+var sendSlack = new SimpleTask("send_slack", "slack_ref");
+
+var fork = new ForkJoinTask("fork_ref",
+    new WorkflowTask[] { sendEmail },
+    new WorkflowTask[] { sendSms },
+    new WorkflowTask[] { sendSlack });
+```
+
+### Do-While Loop
+
+```csharp
+// Fixed iteration count
+var loop = new LoopTask("loop_ref", 10,
+    new SimpleTask("process_item", "item_ref"));
+
+// Custom condition
+var doWhile = new DoWhileTask("dowhile_ref",
+    "if ($.dowhile_ref['iteration'] < $.maxIterations) { true; } else { false; }",
+    new SimpleTask("process", "process_ref"));
+```
+
+### Sub Workflow
+
+```csharp
+// Reference by name
+var sub = new SubWorkflowTask("sub_ref",
+    new SubWorkflowParams(name: "child_workflow", version: 1));
+
+// Inline definition
+var childWorkflow = new ConductorWorkflow()
+    .WithName("inline_child")
+    .WithVersion(1)
+    .WithTask(new SimpleTask("child_task", "child_ref"));
+
+var subInline = new SubWorkflowTask("sub_ref", childWorkflow);
+```
+
+### Start Workflow (Async)
+
+```csharp
+var startWf = new StartWorkflowTask("start_ref", "async_workflow", 1,
+    input: new Dictionary<string, object>
+    {
+        { "param", "${workflow.input.param}" }
+    });
+```
+
+### Wait Task
+
+```csharp
+// Wait for duration
+var waitDuration = new WaitTask("wait_ref", TimeSpan.FromMinutes(5));
+
+// Wait until specific time
+var waitUntil = new WaitTask("wait_ref", "2024-12-31T23:59:59Z");
+```
+
+### Human Task
+
+```csharp
+var humanTask = new HumanTask("review_ref",
+    displayName: "Review Document",
+    formTemplate: "doc_review_form",
+    formVersion: 1);
+```
+
+### Kafka Publish
+
+```csharp
+var kafka = new KafkaPublishTask("kafka_ref",
+    "localhost:9092", "my-topic", "${workflow.input.message}");
+```
+
+### Terminate
+
+```csharp
+var terminate = new TerminateTask("term_ref",
+    WorkflowStatus.StatusEnum.COMPLETED,
+    "Workflow completed successfully");
+```
+
+## Workflow Operations
+
+Using the high-level client:
+
+```csharp
+using Conductor.Client.Orkes;
+
+var clients = new OrkesClients(configuration);
+var workflowClient = clients.GetWorkflowClient();
+
+// Start
+var req = new StartWorkflowRequest(name: "my_workflow", version: 1);
+var workflowId = workflowClient.StartWorkflow(req);
+
+// Get status
+var wf = workflowClient.GetWorkflow(workflowId, includeTasks: true);
+Console.WriteLine($"Status: {wf.Status}");
+
+// Pause / Resume
+workflowClient.PauseWorkflow(workflowId);
+workflowClient.ResumeWorkflow(workflowId);
+
+// Terminate
+workflowClient.Terminate(workflowId, "Reason for termination");
+
+// Restart
+workflowClient.Restart(workflowId, useLatestDefinitions: true);
+
+// Retry
+workflowClient.Retry(workflowId);
+
+// Search
+var results = workflowClient.Search(query: "workflowType='my_workflow'", start: 0, size: 10);
+```
+
+## Workflow Testing
+
+Test workflows with mock task outputs:
+
+```csharp
+var testRequest = new WorkflowTestRequest(
+    name: "my_workflow",
+    version: 1,
+    workflowDef: workflow,
+    taskRefToMockOutput: new Dictionary<string, List<TaskMock>>
+    {
+        { "fetch_ref", new List<TaskMock>
+            {
+                new TaskMock(
+                    status: TaskMock.StatusEnum.COMPLETED,
+                    output: new Dictionary<string, object>
+                    {
+                        { "result", new { data = "test data" } }
+                    })
+            }
+        }
+    }
 );
-var workflowId = workflowExecutor.StartWorkflow(conductorWorkflow);
+
+var result = workflowClient.TestWorkflow(testRequest);
+Assert.Equal(Workflow.StatusEnum.COMPLETED, result.Status);
+```
+
+## AI/LLM Workflows
+
+### Chat Completion
+
+```csharp
+var chatTask = new LlmChatComplete("chat_ref", "openai", "gpt-4",
+    new List<ChatMessage>
+    {
+        new ChatMessage("system", "You are a helpful assistant."),
+        new ChatMessage("user", "${workflow.input.question}")
+    },
+    maxTokens: 500,
+    temperature: 0);
+```
+
+### RAG Pipeline
+
+```csharp
+// Ingest: fetch document and store embeddings
+var getDoc = new GetDocumentTask("get_doc", "${workflow.input.url}", "application/pdf");
+var storeEmb = new LlmStoreEmbeddings("store_emb", "pinecone", "my-index", "docs",
+    new EmbeddingModel("openai", "text-embedding-ada-002"),
+    "${get_doc.output.result}", "doc-1");
+
+// Query: search embeddings and generate response
+var searchEmb = new LlmSearchEmbeddings("search_emb", "pinecone", "my-index", "docs",
+    new EmbeddingModel("openai", "text-embedding-ada-002"),
+    "${workflow.input.query}");
+
+var generate = new LlmChatComplete("generate", "openai", "gpt-4",
+    new List<ChatMessage>
+    {
+        new ChatMessage("system", "Answer using this context: ${search_emb.output.result}"),
+        new ChatMessage("user", "${workflow.input.query}")
+    });
+```
+
+### MCP Agent
+
+```csharp
+var listTools = new ListMcpToolsTask("list_tools", "weather-server");
+var callTool = new CallMcpToolTask("call_tool", "weather-server", "get_weather",
+    new Dictionary<string, object> { { "city", "San Francisco" } });
 ```

Subject: [PATCH 14/19] Add task-update-v2, interceptors, OSS auth
 auto-disable, and schema auto-registration

- task-update-v2: UpdateTaskV2 on TaskResourceApi (PUT /tasks/{taskId}) returns next task
  in one call; WorkflowTaskHttpClient falls back to v1 on 404/405/501 with a sticky flag
  so the server is only probed once; WorkflowTaskExecutor feeds the returned next task
  directly into ProcessTask, skipping an extra poll round-trip

- OSS auth auto-disable: TokenHandler sets _authDisabled on 404/405 from the token
  endpoint and returns null for all subsequent requests, enabling zero-config OSS usage

- Interceptors: new IConductorInterceptor interface (BeforeRequest/AfterResponse);
  Configuration.Interceptors list wired into ApiClient sync and async call paths

- Auto schema registration: [WorkerTask] gains RegisterTaskDef, Description, and
  TimeoutSeconds properties; WorkflowTaskCoordinator accepts optional IMetadataClient
  and batch-registers annotated task defs on startup; new
  AddConductorWorkerWithMetadata DI helper wires everything up

Subject: [PATCH 15/19] Fix: Sticky fallback from task-update-v2 to v1 on HTTP
 404/405

Mirrors Python SDK fix (PRs #387 and #388). When the server returns 404
(endpoint not found) or 405 (Method Not Allowed on older Conductor 4.x),
_useUpdateV2 is set to false permanently so v2 is never retried.
Subsequent calls go directly to v1 without probing the server again.

Also adds InternalsVisibleTo for test project and upgrades test TFM to net10.0.

Subject: [PATCH 16/19] Fix: Wire metrics, EventDispatcher,
 NonRetryableException, and TaskExecLog in WorkflowTaskExecutor

- Add NonRetryableException class: thrown by workers to mark task as FAILED_WITH_TERMINAL_ERROR with no retries
- Wire ConductorMetrics counters/histograms at every poll, execute, and update-task path (was dead code)
- Wire EventDispatcher.Instance at every key lifecycle event (OnPolling, OnPollSuccess, OnPollEmpty, OnPollError, OnTaskExecutionStarted, OnTaskExecutionCompleted, OnTaskExecutionFailed, OnTaskUpdateSent, OnTaskUpdateFailed)
- Catch NonRetryableException separately and set FAILEDWITHTERMINALERROR status
- Append TaskExecLog with full stack trace (e.ToString()) on both NonRetryable and regular failures

Subject: [PATCH 17/19] Fix dead code and duplicate Content-Type header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove _useUpdateV2 flag and unreachable catch clause from WorkflowTaskExecutor;
  the v2→v1 fallback is owned entirely by WorkflowTaskHttpClient which catches
  404/405/501 before they can propagate, making the executor-level flag dead code
- Remove duplicate Content-Type header from UpdateTaskV2/UpdateTaskV2Async; RestSharp
  sets it via the contentType argument to CallApi, adding it to localVarHeaderParams
  was redundant and inconsistent with all other methods in the file

Subject: [PATCH 18/19] Revert .NET version changes to preserve backward
 compatibility

- Revert test project target framework from net10.0 back to net8.0
- Revert Dockerfile base image from sdk:10.0 back to sdk:8.0
- Move task-update-v2 fallback (_useUpdateV2 flag) from WorkflowTaskHttpClient
  back into WorkflowTaskExecutor so unit tests mocking IWorkflowTaskClient
  can properly exercise the sticky fallback behaviour

Subject: [PATCH 19/19] Add OSS integration tests via Testcontainers, clean up
 CI

- Add Testcontainers-based integration tests against conductoross/conductor-standalone:3.15.0
  covering workflow lifecycle (start, pause, resume, terminate) and task
  poll/complete/fail flows
- Mark cloud-dependent tests with [Trait("Category", "CloudIntegration")] so
  they are excluded from the default CI run (require live Orkes server)
- Add integration_tests CI job that runs the new tests directly with dotnet test,
  letting Testcontainers manage the Docker lifecycle
- Remove || true from unit test step now that cloud tests are excluded; unit
  test failures will correctly fail the build
- Update Dockerfile test filter to exclude both CloudIntegration and Integration
  categories from the Docker-based unit test run
