Admob in Windows 8.1 build

Hello!
I am using Cocos2d-x v3.7, building for Windows Phone and Windows 8.1 (universal). Project generated by cocos is pure c++, instead of c# project using c++ as it was in v3.3

My question: is it possible to implement Admob ads sdk (which is c#) in this case? Maybe it is possible to generate c# project somehow?

Best regards

from what i found it is NOT possible:
if main project would be c#, then going from c# to c++ and back to c# is ok.
if main project is c++, then it is NOT possible to use c#

Would be great to find a solution for this.

Does anyone know if it is possible to create a proj.winp8.1-xaml that would be like an upgrade from the proj.winp8-xaml project that used to exist in cocos2d-x 2.x and in the early releases of 3.x?

@stammen @stammen2 Was there a performance reason that the C++/CX style windows phone project was removed and replaced with the proj.win8.1-universal.

This post also has a related discussion. I also added some comments on how I integrated Admob and Flurry into the proj.wp8-xaml in the past.

The following post hopefully will have more information on Windows Phone C++/cx or alternative options soon from @zhangxm or @stammen:
