Lifetime scope for Actor instance

[Flern]

I'm struggling with service resolution for my Actors. I have a command handler pattern that resolves ICommandHandler generic handlers, and I have a repository service that the command handlers use. When I route the command to all the handlers, they use that repository service to store the results in a queue. I configured the repository service as a SingleInstance such that the higher-level Actor method and the generic command handlers would all be using the same instance.

I found out during integration that the SingleInstance lifetime for an Actor service is the entire service - i.e., each Actor instance created during the runtime is using the same repository with a queue intended to serve only one Actor instance. Because of the pattern of generic command handler resolution, I don't think the faux-per-request lifetime scope approach will work for me, but I am really hoping I'm wrong about that.

How would I go about having a shared singleton-like dependency registered within the scope of an Actor instance?

I can provide some sample code if that helps.

Ah, I figured it out.

Looking at the Introductory Blog Post, I saw this:

internal sealed class ActorFactoryRegistration : IActorFactoryRegistration
{
    public void RegisterActorFactory<TActor>(ILifetimeScope container) where TActor : ActorBase
    {
        ActorRuntime.RegisterActorAsync<TActor>((context, actorTypeInfo) =>
        {
            return new ActorService(context, actorTypeInfo, (actorService, actorId) =>
            {
                var lifetimeScope = container.BeginLifetimeScope();
                var actor = lifetimeScope.Resolve<TActor>(
                    TypedParameter.From(actorService),
                    TypedParameter.From(actorId));
                return actor;
            });
        }).GetAwaiter().GetResult();
    }
}

Therefore, the builder.RegisterType<MyConcreteType>.As<IMyServiceType>().InstancePerLifetimeScope() binds the instance to the Actor instance lifetime scope.

I'm very new to DI / Autofac - sorry about the WOB here. Keep up the good work!

No problem @Flern. I'm glad you figured it out. Sorry I didn't get to your question sooner.
