Hi,
I'm accessing a normal data collection in a WCF dataservice, and initially everything works fine. I receive the data correctly and can view the xml in a browser or a tool like LinqPad. But after a few requests, 6 or 9, I'm starting to receive an invalid
xml. The feed element is two times in the xml. All subsequent requests on the same collection have this problem. But when I access another collection the process repeats itself. I get 6 or 9 correct results, and then it starts to fail again.
I'm using an Entity Framework code-first approach. My custom context that's inherited from DbContext is the generic parameter of the DataService<T> class. I let the framework create an instance of this class.
What am I doing wrong, or how can I work around this?
Below are two responses that I captured with fiddler. The first response returned a correct feed, whearas the second response (request 9 in this case) returned an invalid xml.
