Recently after upgrading to latest Telerik binaries in my Silverlight RIA Service application, I noticed a different behavior in the auto generated code. After searching a lot on the issue, came to know that the RoundtripOriginalAttribute was missing in the entity set.
As we can not add the attribute explicitly in a auto generated file, I had a tough time to find out the solution of this issue. Lately, got the solution which I am going to document it here for you.
