I am using ArcGIS runtime SDK for .Net (V100.5) to develop a WPF application. The function for generating an offline geodatabase (xx.geodatabase) is working well, but synchronizing data always has an issue “Unable to synchronize replica.” Does anyone have any idea about this issue? My application’s feature service was published to ArcGIS online and it has one feature layer and a related table. Because the attributes of the feature layer were changed several times, I deleted this service and republished it several time recently, which is the reason which caused the issue? Thanks for your help.
