iResultPattern

A lightweight and expressive result‑handling package designed for .NET applications.
🚀 IResult Pattern – A Clean, Explicit and Production-Ready Result Model for .NET

Stop returning raw exceptions. Stop mixing business logic with HTTP responses. Start modeling results explicitly.

🎯 What Is This Package?

IResult Pattern is a lightweight, production-ready result modeling library for .NET applications that provides a clean and consistent way to represent operation outcomes.

Instead of throwing exceptions for flow control or returning loosely structured responses, this package helps you return strongly-typed, explicit, and predictable results across your application layers.

Perfect for:

• ASP.NET Core Web APIs
• Clean Architecture
• Domain-Driven Design (DDD)
• Microservices
• Event-Driven systems
• Modular monoliths

✨ Key Features

🔹 Explicit Status Modeling

Includes structured result statuses aligned with HTTP semantics:

• Success (200)
• Created (201)
• NoContent (204)
• BadRequest (400)
• Unauthorized (401)
• Forbidden (403)
• NotFound (404)
• Conflict (409)
• ValidationError (422)
• InternalServerError (500)
• ServiceUnavailable (503)

This enables clear and predictable API behavior.

🔹 Strongly-Typed Results

Result<T>
Result

Return data safely with proper status and messages.

🔹 Backward Compatible

Legacy Failure status is still supported (marked as obsolete), ensuring no breaking changes for existing systems.

🔹 Clean Architecture Friendly

Designed to:

• Separate business logic from transport layer concerns
• Improve readability
• Reduce exception misuse
• Provide consistent response contracts

🔹 Lightweight & Dependency-Free

• No external dependencies.
• No magic.
• Just clean, explicit result modeling.

🧠 Why Use This Instead of Exceptions?

Exceptions should represent exceptional conditions — not validation failures or predictable outcomes.

This package encourages:

• Explicit business outcomes
• Better error handling
• Improved API consistency
• Easier testing
• Clearer code semantics

🔥 Example

return Result.Success(data);

return Result.NotFound("User not found");

return Result.ValidationError(errors);

Clean. Predictable. Maintainable.

🎯 Who Is This For?

This package is ideal for developers who:

Care about clean code

• Use DDD or Clean Architecture
• Want explicit and expressive application flow
• Build scalable APIs and services

If you believe that clarity and correctness matter in software design — this package is for you.
