.NET Framework Developer Center

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.

The Workflow Way: Understanding Windows Workflow Foundation
Like any technology, applying WF requires understanding what it is, why it's useful, and when it makes sense to use it. David Chappell explores these points as he outlines the value of WF 4. You won't learn how to write WF 4 applications, but you will get a look at what WF 4 offers, why it is the way it is, and how it can improve a developer's life. In other words, you’ll begin to understand the workflow way.
