Call C# from C++ with Window Runtime Component

Hello,

I follow the doc (http://www.cocos2d-x.org/wiki/How_to_integrate_third_SDK , Calling Model part) in order to call C# from C++ in a wp8-xaml project (windows phone 8.0) but i cannot make it work.

This post ( http://stackoverflow.com/a/14435964 ) really help me, but i am lost at the 5th point (Reference the WinRT library in your C# code).

Here is my stack overflow post about this problem : http://stackoverflow.com/questions/30918909/call-c-sharp-from-c-in-a-windows-phone-8-0-solution

Have you got any idea ?

Thanks
