[Title] Timer Service and UI callbacks [Category] Concurrency Management [Last Updated] 9/7/2006 [Description] 
The download contains an interesting concept – a service that acts like a timer, calling back to its clients on requested intervals. The service actually uses the .NET timer and delegates, and is a nice demo of how to bridge the two technologies - the timer delegates and the WCF callbacks. In addition, it demonstrates WCF ability to marshal the callbacks correctly to the UI thread the client it running on.
