Download the WinFX September CTP...

You will love this drop of WinFX… it has the Windows Workflow Services stuff in there as well as Windows Presentation Foundation (“Avalon”) and Windows Communication Foundation (“Indigo”)…

Just a note – it does work only with the BETA2 build of .NET Framework 2.0 and VS 2005… So don’t try to make this work on top of anything more recent.
