From WCF standpoint, just wondering whether I can leverage anything after upgrade from Silverlight 4 to Silverlight 5? I did some research regarding new features of SL5 and cannot find anything about changes to System.ServiceModel and System.ServiceModel.Web namespaces, is it rigth that nothing were added or am I missing something?
My Questions:
- Have there been any changes to WCF in Silverlight 5?
- If yes, has there been any changes to duplex polling on HTTP?

Tomasz Janczuk wrote a great series of articles on the HTTP Polling Duplex protocol. Specifically, you might want to look at this one which discusses scalability directly.
The gist of it is that in order to provide scalability, you have to support the Duplex Service with a backend bus architecture. The services would be responsible just for shuttling messages from the client to the backend. The backend would be responsible for identifying where outgoing messages should be routed and how to process inbound messages.
