.Net Framework 3.0 Shipped
This Entry is a bit late, but nevertheless .....
This is an additive release to 2.0 which contains Windows Communication Foundation (WCF), Windows WorkFlow Foundation(WF)Windows Presentation Foundation (WPF) and Windows Cardspaces. No new features have been added to the base existing framework
This is the Windows Vista SDK RTM release which also contains the SDK for .Net Framework 3.0 .
Monthly refreshes of WCF SDK can retrieved from https://msdn2.microsoft.com/en-us/library/aa388579.aspx . MSDN Refreshes contain only conceptual and reference documentation updates. Most likely there are no issue with our tools ;)
WCF SDK contains conceptual documentation, reference documentation, tools like Svcutil.exe etc., libs, and header files.
