As expected, Microsoft today shipped Visual Studio 2008 and the .NET Framework 3.5:

The wait is over! Today, Microsoft announced Visual Studio 2008 and the .NET Framework 3.5 have been released to manufacturing (RTM). With more than 250 new features, Visual Studio 2008 includes significant enhancements in every edition, including Visual Studio Express and Visual Studio Team System. Developers of all levels – from hobbyists to enterprise development teams – now have a consistent, secure and reliable solution for developing applications for the latest platforms: the Web, Windows Vista, Windows Server 2008, the 2007 Office system, and beyond.

MSDN subscribers can get Visual Studio 2008 now, but everyone can snag the free Express Editions, which are now available separately, as before, and also in an all-in-one DVD image.
