Inject Failing using "WithParameters" Autofac

Question

I'm trying to register some endpoints I've created, however, Autofac is throwing an exception, saying I haven't registered my BControl class. Here is my registration code:

    builder.RegisterType<GControlEndpoint>().As<IBusConsumer>().SingleInstance();
    builder.RegisterType<BControlEndpoint>().As<IBusConsumer>().SingleInstance();

    builder.RegisterType<BSControlEndpoint>().As<IBusConsumer>().SingleInstance()
      .WithParameter((pi, c) => pi.Name == "bControlEndpoint",
        (pi, c) => c.Resolve<BControlEndpoint>())
      .WithParameter((pi, c) => pi.Name == "gControlEndpoint",
        (pi, c) => c.Resolve<GControlEndpoint>());

And my BSControlEndpoint code is as follows:

  private BControlEndpoint bControlEndpoint;
  private GControlEndpoint gControlEndpoint;

  public BSControlEndpoint(
    BControlEndpoint bControlEndpoint,
    GControlEndpoint gControlEndpoint)
  {
    this.bControlEndpoint = bControlEndpoint;
    this.gControlEndpoint = gControlEndpoint;
  }

Any help would be appreciated.

Autofac error is :

Autofac.Core.Registration.ComponentNotRegisteredException: The requested service 'Sa.BControlEndpoint' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

Answer 1

Add AsSelf to the registration definition of dependencies:

builder.RegisterType<GControlEndpoint>()
   .As<IBusConsumer>()
   .AsSelf()
   .SingleInstance();

builder.RegisterType<BControlEndpoint>()
    .As<IBusConsumer>()
    .AsSelf()
    .SingleInstance();

Also this should make WithParameter call not needed:

builder.RegisterType<BSControlEndpoint>().As<IBusConsumer>().SingleInstance();

Another option is to look into keyed dependencies registration (docs)
