Multi Room Chat Application using SilverLight 4.0 and PollingDuplex

I'm lo开发者_StackOverflow社区oking for a sample or guidelines to build a multi room chat application using SL 4.0 and PollingDuplex.

Any help ?

Dan Wahlin did a great article on this topic:

On SilverlightTV you can watch an episode about Silverlight 4.0 and Duplex communication:

There was a session on NDC 2010 about communication with Silverlight 4, but I can't find the link to the video, sorry.

Hope that helps you a little bit.
