If you are a .NET Developer and want to create workflows, but have no where to host them then this may be for you. You create your WF in Visual Studio using some WCF constructs, you run a tool to create a BizTalk orchestration wrapper, and then deploy the wrapper and workflow to the BizTalk server to host it.
To try this out head to the Connect Site for this project, complete the survey, download the sample code and do the walk through.
There are some Prerequisites for the walkthrough and I engourage you to read Paul Andrews blog post that has more details.
Jon Flanders also has a recorded video demo of this you can see here.
