Finally - the confusion is complete: WinFX is now NetFX. Huh?
The (likely) final name for the collection of .NET APIs formerly know as WinFX 3.0 (aka Avalon, Indigo and Workflow, but NOT WinFS) have a new name and community portal: They are now called NetFX and hosted at http://netfx3.com/, with Indigo/WCF being located at http://wcf.netfx3.com/.
