Upcoming Changes to .NET Framework 4:
Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF)

In the .NET Framework 4, there have been significant enhancements within the Windows Communication Foundation (WCF) 4 and Windows Workflow Foundation (WF) namespaces. .NET developers can use these technologies either independently, or together, to eliminate the tradeoff between ease of service authoring and performant, scalable services. This Developer Center helps you navigate the developer-oriented information and documentation for the new versions of WCF and WF, as it is released to the public.
