I already had C# Express 2010 since I've worked with Windows Forms some, but I wanted to started messing around with games for 360. When I went here to download the free tool kit including XNA: http://create.msdn.com/en-us/home/getting_started the install came with Visual Studio C# Express 2010 for Windows Phone 7. They seem to be labeling everything Windows Phone 7 and ignoring 360 so do I use standard Visual Studio C# Express or the Windows Phone version, and what's the difference (if any)?
I really don't have any interest in Windows Phone 7 currently and I find it irritating how it's all they're pushing.
EDIT: Removed what my friend said since he now says he's not sure. :)
