C++ OpenGL ES Viewer in C#

I have created a tutorial which shows how one can use existing C++ OpenGL ES to create a 3D view inside a C# (Xamarin) Application for Windows 8.1 (Store) Windows Phone 8.1, Android and sort of iOS. This is something that I recently needed do do for a project of mine. You can check it out at C++ OpenGL ES Viewer in C# and I you like it, please vote for me in the "Coded Creations" competition on Instructables :)
