MessagePipe.Interprocess - Scope issue on running in none production environment | with scope validation (ValidateScopes)

[gszdev]

Hi,

I'm evaluating the MessagePipe.Interprocess using the NamedPipe.
I'm using the IDistributedSubscriber within a scoped Service and get the following exception if running inside none production environment (DOTNET_ENVIRONMENT != "Production") like development or staging.
Running the same code in a production enviornment works, but running it in an devleopment environment it fails.
This is because scope validation (ValidateScopes) not active and not running in production enviornments.

Exception details:

System.AggregateException
  HResult=0x80131500
  Message=Some services are not able to be constructed
  Source=Microsoft.Extensions.DependencyInjection
  StackTrace:
   at Microsoft.Extensions.DependencyInjection.ServiceProvider..ctor(ICollection`1 serviceDescriptors, ServiceProviderOptions options)

   at Microsoft.Extensions.Hosting.HostApplicationBuilder.Build()
   at Demo.IpcTests.dotNetFxConsoleApp.Program.<Main>d__0.MoveNext()

  This exception was originally thrown at this call stack:
    [External Code]

Inner Exception 1:
InvalidOperationException:

I assume the following is causing the issue. Inside NamedPipeDistributedPublisherSubscribercs (lifetime: singleton) a NamePipeWoker (lifetime: scoped) is injected:

MessagePipe/src/MessagePipe.Interprocess/NamedPipeDistributedPublisherSubscribercs.cs

Line 37 in 94ec087

public NamedPipeDistributedSubscriber(NamedPipeWorker worker, MessagePipeInterprocessNamedPipeOptions options, IAsyncSubscriber<IInterprocessKey, IInterprocessValue> subscriberCore, FilterAttachedMessageHandlerFactory syncHandlerFactory, FilterAttachedAsyncMessageHandlerFactory asyncHandlerFactory)

Changing the InstanceLifetime from Scoped to Singleton for NamedPipeInterprocess is workaround, maybe:
.AddNamedPipeInterprocess(Demo.IpcTests.Services.Constants.PipeNames.DotNetPipe, namedPipeOptions => {namedPipeOptions.InstanceLifetime = InstanceLifetime.Singleton;
})

Does someone know how to solve this issue? Or I'm doing some wrong?
