I am facing this problem with only Windows Phone solutions. My old solution for a pc game, works fine. Can anyone help me what is the issue?
Till now, I have tried to reinstall windows phone tools. Source code is downloaded from MSDN’s official XNA tutorial page. I checked GAC too, and libraries for PC version are already there. But, libraries for XBox and Phone version are not there at all (like XNA.Framework.Avatar, XNA.Framework.Touch). I am unable to figure out, why this is happening, considering I used MS’s default installer for phone tools. All the dlls exist in ProgramFiles/XNA/v4.0 folder, but somehow they are not registered to GAC.
Ok, reinstalled XNA 4.0 and phone tools, same issue. It is just not registering the assemblies at all. What to do?
I had this problem before.
Try installing the “Games for Windows” component

Then install XNA again.
It worked for me.
