Remarks
You can handle the NonPersistentObjectSpace.ObjectsCountGetting event to supply custom logic for calculating the GetObjectsCount result. If the ObjectsCountGetting event is not handled, or if the ObjectsCountGettingEventArgs.Count is null, the GetObjectsCount method calls the IObjectSpace.CreateCollection method to calculate the count.
