I can't make a Visual Studio 2010 XNA Windows Game project. When I do, I receive the following error message:
Now, I already tried running "devenv.exe /InstallVSTemplates" with no luck. This command executes just fine, but all it does is to create duplicates of the already existing "XNA Windows Game" project templates.
Upon opening these duplicates, I get an object null reference exception from Visual Studio.
What's going on? All of this worked just 1 month ago. Since then, I've been doing some development with Windows Phone Mango SDK 7.1 RC. Could this be it? I'd be very unhappy to uninstall this in order to get it to work.
Please help me.
