MIX 09:Duplex Services sample does wether build nor run!

Hi All !

Is it possible for someone to publish a buildable/compilabe version???? It is mentioned to be updated to SL3 and I have SL3 and all tolls, but building the solution fails.

I just cannot imagine, the samples do not build :-(

Error 1 The type or namespace name 'PollingDuplexBindingElement' could not be found (are you missing a using directive or an assembly reference?) D:\dxchg\DOWNLOAD\Develop\Source\MSDN--Silverlight-WCF-DuplexChannel-sample\unpacked\DuplexSample\ChatWebApp\DuplexService.cs 29 21 ChatWebApp

Any help would be great!

You need to manually add System.ServiceModel.PollingDuplex.dll by right-clicking "Add Reference|Browse" on Reference of ChatWebApp. It's usually in C:\Program Files\Microsoft SDKs\Silverlight\v3.0\Libraries\Server.

Also there is a Silverligh 4 RC Video Chat sample, which uses almost the same service, so you should be able to get that to work easier.
