Alex, I don't want to say it is impossible, but it would certainly be very hard. DuplexMode.MultipleMessagesPerPoll method uses .NET Binary encoding, which is a binary protocol that allows tunneling SOAP messages within. Parsing and constructing this protocol in JavaScript would be a challange.

If you need to run your wcf services in compatibility mode, In .NET 4, you can do this in `Application_BeginRequest`

if (Context.Request.Path.EndsWith("xxx.svc"))
Context.SetSessionStateBehavior(SessionStateBehavior.Disabled);

Sriram, no changes should be necessary on either Ajax client or server when moving from Silverlight 3 to Silverlight 4, unless you want to levereage the new DuplexMode.MultipleMessagesPerPoll mode in Silverlight 4. The latter would require rather substantial changes of the client implementation which I have not attempted.

Hi Tomasz,
Can we make a none silverlight client program (such as WCF library and it's hosted by Windows Service) call the PubSubService.svc to publish a topic?

Christian Weyer encountered a bug in the sl3duplex.js AJAX library which prevents the client from initiating a new poll request when the previous poll was timed out on the server. I have just updated the sample solution with a fixed version of sl3duplex.js. The new sample is available at the same location at http://janczuk.org/code/samples/PollingDuplexSampleAjax.zip.
