Windows Workflow Foundation Web Workflow Approvals Starter Kit
"This starter kit is a Visual Studio 2005 project that demonstrates using Windows Workflow Foundation for simple task oriented workflow in an ASP.NET web application. A workflow model is used to automate work order requests at a small example company. It includes three pre-defined roles which each play a part in the work order creation, approval and monitoring. The starter kit may be modified for other workflow models to suit other small web based task management systems."
