Is there anything about Windows Workflow Foundation (WF) that you would like to know and feel is an appropriate topic for this blog? If so, please add a comment to this post. I will use the comments as seeds for future postings. Even if someone has already posted your specific question, please add your own comment as well so that I can do a better job prioritizing.
Note that posting here does not in any way guarantee that I will respond, but I will try to do the best that I can. Another good resource for general WF questions is the http://www.windowsworkflow.net. This site has articles and samples of its own as well as links to other blogs and related MSDN forums.
