Over a course of 10 days, October 3rd on, programmers came to Microsoft to test drive the WF APIs and help us determine how usable our APIs are. We also recorded a video with one of the participants, Nancy Perry Lincolin, Steven Clark, James Conard, and Dennis Pilarinos. Check www.WindowsWorkflow.net for the video. Check www.microsoft.com/usability for more information on Microsoft usability research and to see how you can help Microsoft ship great easy to use software.
