Hello,

A problem occured when I call the ServiceFeatureTable.LoadStatusChanged, It would not raise the event,

var serviceTable = new ServiceFeatureTable(new Uri("")) { FeatureRequestMode = FeatureRequestMode.ManualCache };

serviceTable .LoadStatusChanged += serviceTable _LoadStatusChanged;
CurrentMap.Tables.Add(serviceTable );
