JSon serialization using azure mobile

Question

I am using azure mobile service (backend sdk 1.x) and I am serializing table objects in Json.

config.Formatters.JsonFormatter.SerializerSettings.TypeNameHandling = TypeNameHandling.Objects; 

I would like to have $ type names serialized with each object. This used to work until I started using Json.net directly in another class. Now every time I get json from the controller, the $ type property exists, but it's empty.

I strongly believe that the newtonsoft library is not properly associated with azure web material (I have done several experiments with Json.net custom serializers, and they don't get called when TableController returns the result to the client).

Any ideas for fixing the problem?
