  7. Draw a line from the receive to the send reply.  Of course you can insert other activities in between the two as well.

To make it simple I created an Item template named the WCF Flowchart Service in the Visual Studio Gallery for creating this type of service in your project.  You can access it directly from Visual Studio 2010 by looking in the online templates.
