Resolving type with Microsoft Unity and inherited interfaces

I have this classes and interfaces

public interface IA{
  void Load();
}

public interface IB : IA{
}

public class B : IB{
   public void Load(){
      //some code
   }
}

and I register the IB for type B

Microsoft Unity resolves IB to correct type which is B, but when I try to call Load it shows an error IB does not contain a definition for 'Load'

Update

This is my unity configuration

var unityContainer = new UnityContainer();

unityContainer.RegisterType<IB, B>();

var obj = unityContainer.Resolve<IB>();
obj.Load()

IB does not contain definition for Load() but IA does, so you either have to resolve IA to B via unity or once you resolve IB, cast it to IA.

Update 1: I have to agree with other folks here, that the OP code does work and resolve correctly with Unity (tested with .NET 4.5.2 and Unity 2.1.505.2). I am not sure why my suggestion above solved the OP issue, so there has to be some details omitted in the original question.

Update 2: Working Fiddle based on @will's https://dotnetfiddle.net/FoYQSM
