Remarks

The EndSaveChanges 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 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 it was before EndSaveChanges was called.

If an error occurred and processing stopped during an operation, the State will remain unchanged.
