.NET 3.5: How to host WF runtime in WCF?

Question

I need to find a tutorial for hosting the Workflow Foundation Runtime in WCF using .NET3.5. Does anyone know any good links specifically on this?

UPDATE: Preferably, it should have some code samples on the implementation.

Answer 1

I've found an article that I've yet to thoroughly review, but it meets my requirement of having code samples and uses .NET 3.5.

UPDATE: The article is what I wanted, so I'm marking this as my answer.
