I want to download VS 2010 Ultimate through my MSDN licence, but I don't see one for the 64-bit. There's Visual Studio Team Foundation Server 2010 (x86 and x64) - DVD (English), but is that just the server or can I use it for dev too?
There is no 64 bit VS 2010. If you can, you want to download the ultimate edition. It will give you everything you need to write along with the test tools etc. It will also allow you to access to use the premium edition code contract generation.
Team Foundation Server isn't an IDE. It's a code/project management tool.
