jamesigoe / publisher

This sample combines the Facade pattern with the Publisher (Observer) pattern. The primary class, based on the ISubscriber interface, is fairly complicated to use, requiring delegates, threading, and asynchronous callbacks. The facade, based on ISubscriberFacade, encapsulates all the methods required to work with the Windows Communication Foundation (WCF) service , handling threading, delegate creation, and asynchronous callbacks internally, so that that the clients only need to create the object. I wrote the encapsulating client to ease the adoption of the WCF service for legacy clients, seeing that the code complexity was likely a hurdle.
