由于WinFX这个名字给开发人员造成了很多困惑，弄不清楚WinFX和Framework的关系，微软决定将WinFx更名为.NET Framework 3.0。
The change is in name only and will not affect the technologies being delivered as part of the product. The .NET Framework 3.0 is still comprised of the existing .NET Framework 2.0 components, including ASP.NET, WinForms, ADO.NET, additional base class libraries and the CLR, as well as new developer-focused innovative technologies in WPF, WCF, WF and WCS:

The .NET Framework 3.0 will still ship with Windows Vista, and will be available down-level for Windows XP and Windows Server 2003 as planned.  This change doesn’t affect in any way the ship schedules of either Windows Vista or the .NET Framework 3.0 itself.
汗死了，2.0还没有搞熟呢，3.0今年就要发布了。。。
