How do you extend a C# interface in C++/CLR?

I'm really frustrated with this one. I'm trying to extend a C# created interface in C++/CLR. The interface has one method and I've declared it in my class, but the compiler keeps telling me that I must still provide an implementation for the interface method. What more can I do? What am I missing!?

Does anyone have any e开发者_开发百科xamples of how to extend a C# interface in CLR?

I figured it out! I needed to make the implementation of elements virtual. I hope this helps other people with this same issue.
