When processing events why create an async scope?

[iem365-michael]

Hi all,

Just looking to expand my understanding; appreciate any support.

In RabbitMQEventBus.cs when processing an event within ProcessEvent there is a new async scope created.

await using var scope = serviceProvider.CreateAsyncScope();

This is then used to resolve the keyed IIntegrationEventHandlers.

foreach (var handler in scope.ServiceProvider.GetKeyedServices<IIntegrationEventHandler>(eventType))

As the handlers are injected as transient:

eventBusBuilder.Services.AddKeyedTransient<IIntegrationEventHandler, TH>(typeof(T));

This scope appears redundant to me, and I would look to resolve the services directly from the service provider?
