Windows Workflow Foundation (WF) allows developers to create declarative application logic for quicker development, simplification of complex tasks, and management of long-running business logic. Learn how to use WF in your web applications, web services, or any .NET application. This is the first in a series of short courses on WF 4, and lays the foundation for other courses. Future courses will focus on particular development areas such as activity development, workflow services, hosting, designers, etc. This course is focused on WF in .NET 4. No knowledge of WF in .NET 3.x is assumed or required/recommended. For users interested in WF 3 (used in SharePoint 2007/2010), we recommend the Windows Workflow Fundamentals course which covers WF 3.
