Question

I have the following problem:

I have some classes and interfaces in the first assembly:

public interface IA {}
public interface IB : IA {}
internal class C : IB {}

and class C is registered in the Unity container in this assembly.

Container.RegisterType<IB, C>();

and now I want to register something like

Container.RegisterType<IA, C>();

in the another assembly, but class C is not accessible. And

Container.RegisterType<IA, IB>();

does not work, because IB is interface.
How can I link base interface IA with already registered IB?

Thanks a lot!

You simply cannot use internal type inside another library but you can resolver IB so:

Container.RegisterType<IA>(new InjectionFactory(x=>x.Resolve<IB>()));
