Remarks
The SaveChanges method returns a DataServiceResponse object that contains a series of OperationResponse objects, each of which contains a sequence of EntityDescriptor or LinkDescriptor instances that represent persisted changes.
For successful operations, the State property of the descriptor is set to unchanged and the new values for insert and update operations are merged according to the merge settings.
For operations with errors, the State of the descriptor will remain the same as they were before SaveChanges was called.
If an error occurred and processing stopped during an operation, the State will remain unchanged.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
