The RTM release of Windows Communication Foundation (lovingly but heretically referred to as "Indigo" -- some names just stick) went live on MSDN today as part of the .Net Framework 3.0 download[1], which makes this a pretty darn cool day. Go build some apps!
Here are links that will help you with that:
Microsoft Windows SDK for .NET Framework 3.0
Microsoft Visual Studio 2005 CTP Extensions for .NET Framework 3.0 (WCF & WPF)
Microsoft Visual Studio 2005 Extensions for Windows WorkFlow Foundation
Enjoy the bits...
[1] Vista release Coming Soon, as part of a bit larger redist (one that includes the whole OS). Stay tuned.
