Typed WF Communications Details

If you downloaded the samples from my previous two forays into WF communications programming, you probably couldn't get them to build. The problem is that when I packaged things up, I removed the bin directories. I haven't figured out just why this causes everything to stop building, but with the help of Dennis Pilarinos, I rearranged the two projects into three:

1. communications interface (CommunicationLibrary): the data exchange service interface definition, compiles into CommunicationLibrary.dll

2. communications activities (WorkflowProject1): uses a pre-build step to generate the typed activities generated from the communications library using the wca tool, references CommunicationLibrary.dll and compiles into WorkflowProject1.dll (nice name, eh? : )

3. application (EventSinkAndMethodInvoke2): the app that uses the typed activities, references both CommunicationLibrary.dll and WorkflowProject1.dll

It's only by separating the communications activities into a separate assembly that things can build and rebuild reliably. You can download the newly configured code here. Enjoy.
