One question I was asked during my web cast yesterday about calling WCF services from Silverlight is if the service could be a workflow service. I said - "Of course" - not knowing that it was a little more complex than that :) That said - here is a sample.

The key to making it work is setting the instanceid context to null on the server when the "last" operation is called - in this case the operation implemented inside of the eventhandler which causes this state-machine workflow to move to the completed state (so that the client can then start a new workflow). I hope to find an more elegant and automatic solution - but this works for now (Hope you are listening Jason from the webcast - this ones for you ;-)) Check out my BizTalk R2 Training .
