Developing for Windows Phone 8.1 and am very impressed with application response, visually appealing mapcontrol, etc., but seems we have taken a step backwards with not allowing editing to local data. This functionality was/is present in ArcGIS for Windows Mobile. Looking to develop an application with many disconnected users that never have a need to update data either direction really. I am potentially looking at the service based geodatabase as creating a template and using this in offline mode for all of the users. Anyone see issues with this, or can think of a better solution? I think handling all features as graphics would be a performance nightmare, but could be wrong. Hopefully local non-service based editing will be available in subsequent releases. Any and all suggestions appreciated!
