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. :)
I found the answer hidden in a blog post on the XNA blog: Link
Here's the quote, they really should make this kind of information easier to find IMO:
For existing XNA Game Studio users, you’ll notice a change: XNA Game Studio 4.0 is part of the Windows Phone Developer Tools. These tools provide an amazing array of features all built on Visual Studio 2010; for those that don’t have a version of Visual Studio 2010 installed, the Windows Phone Developer Tools will automatically install the Visual Studio 2010 Express for Windows Phone version for you. (Don’t worry – it works great for Windows and Xbox 360 development, too!)
So I don't know if anything is truly different, but it sounds like it at least has everything from the normal C# Express, if not more.
