  • Duplex Communication with WCF in Silverlight 4 (Silverlight TV #34)

    eventually got it working by qualifying the BindingExtension with a version,culture and publickeytoken. Also had to put a receiveTimeout on the binding....

     

    <

     

    and

     

     

    add name="pollingDuplex" type="System.ServiceModel.Configuration.PollingDuplexHttpBindingCollectionElement, System.ServiceModel.PollingDuplex, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

    <pollingDuplex>
            <binding name="myPollingDuplex" duplexMode="MultipleMessagesPerPoll" receiveTimeout="00:30:00"/>
    </pollingDuplex>

  • Duplex Communication with WCF in Silverlight 4 (Silverlight TV #34)

    Hi Tomasz,

     

    I am very new to programming and I am going through this demo, building it from scratch from your video using Visual Web Developer 2020 Express. I am running Silverlight 4 on Windows XP.  I get to the end of building the server WCF service, press <F5> to run the project. All is well until I try to access the Meta Data by typing the ChatService.svc URL on my localhost. Then I get the error message

     

    "Configuration binding extension 'system.serviceModel/bindings/pollingDuplex' could not be found. Verify that this binding extension is properly registered in system.serviceModel/extensions/bindingExtensions and that it is spelled correctly."

     

    I gathered from other posts on your blogsite that this is a common problem. I have de-installed and re-installed silverlight to no avail. Any thoughts? What am I doing wrong?
