Two areas I have spent a fair bit of time on in the last 6 months are SaaS and Workflow Foundation. Workflow Foundation is a great technology that seems to fit well into the SaaS world of "configuring business processes" - which is one reason why Workflow Foundation is used in our Litware sample SaaS application. But what I (and you) really want to see is real world examples of SaaS application using Worklow Foundation. I am pleased to say we have such an example covered by Ron Jacobs as a series of video interviews with the development team. The Remend Case Study is most definitely worth a watch. Let me know what you think of them.
P.S. I found this blog entry in a drafts folder. I can't remember what else I was planning to write - oops! Enjoy!
