Hello,

I am using WCF Ria Services beta in my silverlight application. I have a long running task on the server which keeps writing its status to a database table. I have a "GetTranslationProgress" Ria Service Query method which queries the state to get the status. This query method is called continuously at a regular interval of 5 seconds until a status = Finished or Error is retrieved.

In some cases if the task on the server is running for a long duration 2-3 minutes then I receives this error:-

Load operation failed for query 'GetTranslationProgress'. The server did not provide a meaningful

reply; this might be caused by a contract mismatch, a premature session shutdown or an internal

server error.

at System.Windows.Ria.OperationBase.Complete(Exception error) at System.Windows.Ria.LoadOperation.Complete(Exception error) at System.Windows.Ria.DomainContext.CompleteLoad(IAsyncResult asyncResult) at System.Windows.Ria.DomainContext.<>c_DisplayClass17.b_13(Object )

The error occurs intermittently and I have no idea what could be causing this error. I have checked most of the forums and sites but I have not been able to find out any solution to this issue.

Please help.
