Telerik controls problem on azure with RX

[Marco]

Hello,

In our project we use the telerik controls (Q3 2011) for silverlight. We use the datagrid  a lot in combination with Reactive Extensions with Silverlight 4. We use reactive extensions to complete multiple webservice calls in a simple way like below (this is a simple representation)

var webserviceCalls = from allRiskAspectResponse in client.DoCall(parameter1)
                from allRiskEffectsResponse in client.DoOtherCall(parameter2)
                select new { allRiskAspectResponse, allRiskEffectsResponse };

 webserviceCalls.ObserveOnDispatcher().Subscribe(result =>
 {
//do something with the result of the webservice calls
});

After that we set the result in an ObservableCollection in the viewmodel and bind that to the itemsource of the telerik datagrid. This works perfect on our local machines and our seperate Test enviroment. But as soon a we deployed this code to azure if fails with the error displayed in the screenshot.

The problems started when we used the telerik silverlight controls in combination with reactive extensions. We also tried to use it with the original datagrid and that works as expected without any errors. I googled a lot about it but couldn't find any information so i ask here.

With kind regards,

Marco
