So if you are interesting in how to integrate WCF and WF today (yes all the cool new WCF/WF stuff in Orcas is really cool - but still some number of months away) - please come to my pre-con at TechED US - https://www.msteched.com/public/precons.aspx#PRCN15 I'll be doing it with my good friend Richard Blewett - which should be a good combination of technical learning and fun.
