In the name of dispelling confusion, Microsoft has decided to rechristen WinFX as .Net Framework 3.0. We’re still not 100% sure this rebranding will achieve Microsoft’s goal, given that the branding (and rebranding) around .Net has been pretty darn confounding. But it’s official: Windows Communications Framework (Indigo) + Windows Presentation Framework (Avalon) + Windows Workflow Foundation (WinOE) + InfoCard (now known as Windows Cardspace) = .Net Framework 3.0. If you want a shorthand way of describing .Net Framework 3.0, it’s the new Windows programming model that commences with Windows Vista.
Rechristens, WinFX, Framework 3.0
