Using the CCR to Provide Robust Interaction With WCF Services

This post provides a complete implementation of a WinForms client calling a WCF service using Microsoft Concurrency and Coordination Runtime (CCR). We were able to write clean code that correctly interacted with the UI thread giving us a fully-responsive UI, were able to cache the service requests by posting them into the wrapper’s input port, we NEVER blocked a thread while waiting for asynchronous I/O, and handled all failure conditions cleanly.
