While attending Microsoft TechEd 2006 in Boston, I became aware of a blog posting that was posted on Friday by S. Somasegar (Microsoft Vice President of Developer Tools at Microsoft) where he announced that WinFX is now formally the Microsoft .NET Framework 3.0. You can read the posting by S. Somasegar here:.NET Framework 3.0
Aaron Stebner’s WebLog has posted on the .NET Framework 3.0 stating that the change is merely a naming change and that we can expect this framework to ship along with Windows Vista and will be also available as a redistributable package on Windows XP and Windows Server 2003. You can read Aaron’s comments regarding Microsoft .NET 3.0 here.
Microsoft .NET Framework 3.0 (WinFX) development is currently supported through the download of additional components for Visual Studio 2005, these components can be downloaded from the Microsoft .NET Framework 3.0 homepage.
