Pub/sub sample using HTTP polling duplex WCF channel in Microsoft Silverlight 3

We now have a sample implementation of a pub/sub scenario that uses the HTTP polling duplex WCF channel shipped in Silverlight 3. The sample demonstrates some of the best practices for implementing performance-conscious duplex scenarios using the PollingDuplexHttpBinding, as well as the usability benefits of duplex WCF proxies generated using the Add Service Reference feature of Visual Studio in Silverlight 3. Check out the full description of the polling duplex sample and access the source code, then let us know what you think.
