    [ServiceBehavior(IncludeExceptionDetailInFaults = true)]
    public class Northwind : DataService<NorthwindEntities>
        // This method is called only once to initialize service-wide policies.
        public static void InitializeService(DataServiceConfiguration config)
            // Grant only the rights needed to support the client application.
            config.SetEntitySetAccessRule("Orders", EntitySetRights.AllRead
                 | EntitySetRights.WriteMerge
                 | EntitySetRights.WriteReplace);
            config.SetEntitySetAccessRule("Order_Details", EntitySetRights.AllRead
