Windows Workflow Foundation Web Workflow Approvals Starter Kit
Microsoft built a new starter kit for Workflow foundation and ASP.NET. It is a web application that includes task-oriented workflow using Windows Workflow Foundation.
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
