Last night Microsoft launched the final release of the .NET Framework 3.0 (formerly WinFX). I ran the quick installer on two machines today, and the setup worked perfectly both times. Not even a restart required. If you’d like to check out the release notes before installing, they are available here.
This is a very important release for developers using Microsoft technologies, because it makes some key Windows Vista components available for Windows XP and Windows Server 2003. Of course the developer tools aren’t quite ready for primetime, but they’ll get there.
