Install XNA 4.0 Visual Studio 2010 Windows 8
I installed windows 8 a month ago and now want to add xna game studio 4.0 to my visual studio 2010 ultimate. I downloaded the xna installer from http://www.microsoft.com/en-us/download/details.aspx?id=23714 and ran the setup. First it said something about compatibility issues but the setup continued. after it finished I restarted the computer and wanted to make a xna project but its not showing in the c# drop-down menu. So i took a look at the %programm files(x86)%/Microsoft viual studio 10.0/Common 7/IDE/extensions/Microsoft, but there was no xna folder. Did I do something wrong or is windows 8 having some issues with vs2010 and xna 4.0?
Answer
XNA is not officially supported on Windows 8 and never will be because Microsoft simply gave up on it.
This solution explains how to install XNA on Windows 8 but clearly if you want a stable development environment you will have to develop on a Windows 7 machine but remember that even if you are skilled on XNA, the Framework itself is doomed and bound to disappear.
If you want to keep developing with C# on Windows 8 I can only recommend you move to MonoGame which is an open source implementation of the XNA 4 API for multiple platforms using the CLR or Mono so basically most of your XNA knowledge can be reused in MonoGame.
