Windows Workflow Foundation is a workflow engine, programming model and set of tools for developers to rapidly build workflow-enabled applications. Windows Workflow Foundation is a set of activities that coordinate people and software. With it, Microsoft is redefining workflow by incorporating it into a mainstream development platform and supporting both human and system workflow across client and server scenarios. Workflow capabilities will be available to developers via WinFX, the new programming model for Windows Vista. Developers can workflow-enable applications using the familiar and popular Visual Studio development tools. Microsoft also announced plans to use Windows Workflow Foundation to workflow-enable the next version of Microsoft Office products, code-named Office Ã¢â?¬Å?12,Ã¢â?¬? BizTalk Server and Microsoft Dynamics.
