What is the advantage of Windows Workflow Foundation?
Windows Workflow Foundation (WF) is a technology developed by Microsoft for defining, executing, and managing workflows. This technology is part of .NET Framework 3.0 and is native to the Windows Vista operating system. It has been backported to the Windows XP and Windows 2003 Server operating systems. The .NET Framework 3.0 “Workflow runtime” provides common facilities for running and managing the workflows and can be hosted in any CLR application domain. A new XML-based language XAML is commonly used for declaring the structure of a workflow. However, the workflow may also be expressed in code using any .NET-targeted language, such as C#.
