With the new workflow extensions added to .Net 3.5, some of the ISVs I work with have expressed a renewed interest in the Workflow Foundation. I found myself covering certain topics more frequently than others, so I decided to start a short how-to series that addresses some of the most common questions.
These screencasts last about 12 minutes each and will hopefully get you quickly started with your own custom workflows and activities.
Sample code is attached to part 2 and I'm still planning at least one more part on advanced activities and workflow services. I'll post that link when the screencast goes up.
