Is it possible to have a C#/cx project in windows phone 8.1 with Cocos2d-x 3.7? Like the proj.wp8-xaml, but upgraded to proj.wp8.1-xaml?
Were there performance reasons that proj.wp8-xml was removed and replaced with the pure C++ project proj.wp8.1-universal somewhere between 3.0 and 3.7?
In the previous proj.wp8.xaml I think was a c++/cx project.
I’m not certain how to verify that is what it is called, but it was a c# based project with a C++ lib extension, so I think it was.
@ghua, not sure why you said “going from c++ to c# is not allowed”.
With that project in Cocos2d-x 2.2.6 and 3.0 I was able to integrate Flurry Analytics and Admob, with C++ calling into the c# code to show interstitial ads and to send Flurry events. But those projects targeted Windows Phone 8.0, not 8.1.
Here is some information that I found that seems to reflect what I did.

I added C# objects and code to MainPage.xaml.cs and a class called NativeEventHelper.cpp where the C++ code lives. If I recall, I just copied the style of C++ to C# code and C# to C++ code that was already implemented in these classes. These two classes then glued the C++ and C# together similarly to how JNI works with Android.
Not having such a feature in the Windows Phone 8.1 Universal project makes it kind of useless.
