Is it possible to use Workflow ReceiveActivity with independently written WCF service?

Question

Suppose I had a WCF service that I have coded up, like Clemens Vasters's XML-RPC with WCF, and want to stick a workflow behind it on the server side.

Is this possible to do with Windows Workflow? If so, how?

The toolbox ReceiveActivity appears to create the WCF service for me.

I'd prefer the answer in terms of Workflow 4.0, if possible.

Answer 1

It depends a bit on the service contract as plain WCF has options not exposed by a workflow service. But other than that it should be perfectly possible to create a workflow with a Receive activity to have the same service contract. That leaves the URL but using URL rewriting in IIS should be able to redirect the original URL with its svc extension to the new URL with its XAMLX extension.
