  1. Use Tracking
  2. Unit Tests
  3. Use Timeouts

In this episode I'll show you some sample code that illustrates these three rules

Maybe you haven't thought of them as wizards, but multi-step processes such as checkout or registration are utilized by many websites. In this episode, Muhammad Usman from the Microsoft Product Quality team will show you the new system they are building to create product support wizards with Windows Workflow Foundation. In the past, even simple changes to a support wizard required a coding project. With ASP.NET MVC and WF4 together, support analysts will be able to author a self-help wizard using a custom built authoring tool and deploy it to the web as a XAML workflow.
