Just when people started getting used to WinFX and its underlying technologies... they have changed the name again :-/
According to S.Somasegar
When speaking to developers about WinFX one question that repeatedly comes up is, “WinFX sounds great, but what happens to .NET?” .NET Framework has becomes the most successful developer platform in the world. Developers know and love .NET.
The .NET Framework has always been at the core of WinFX, but the WinFX brand didn’t convey this. The WinFX brand helped us introduce the incredible innovations in terms of Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), Windows Workflow Foundation (WF) and the newly christened Windows CardSpace (WCS) formerly known under the codename “InfoCard.” The brand also created an unnatural discontinuity between previous versions of our framework and the current version.
With this in mind we have decided to rename WinFX to the .NET Framework 3.0. .NET Framework 3.0 aptly identifies the technology for exactly what it is – the next version of our developer framework.
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:
So lets embrace .net 3.0 and keep .net rocking!
