For synchronizing with central operation, there are 4 steps. 1) Save to local (before save to central) - Serializes the streams from memory to local disk cache;2) Reload latest - Downloads the streams from central model on server and merge them into local memory; 3) Save to central - Uploads merged streams from local memory to server central model; 4) Save to local (after save to central) - Serializes the merged streams from memory to local disk cache;
For document open operation, just download the model from server and then open it;
It is NOT recommended to deal with time-consuming work when handling WorksharedOperationProgressChanged event, otherwise it would increase synchronizing with central or model open time.
