Interface implementation in WinRT class

Question

In C++/WRL I can declare and implement interface explicitly, like:

In IDL:

 

    interface IMyInterface : IInspectable

    ...

In C++:

	class MyComponent :

		public RuntimeClass<IMyInterface>

        ....

How can I do the same for C++/CX? 

	public ref class WinRTComponent  : IMyInterface??? sealed
        ...

Answer 1

You should be able to do something like this:

public interface class IFoo {
  void bar();
  property int p;
};

public ref class Foo : IFoo {
public:
   void bar() { }
   property int p;
};

Thanks,
