A PoC illustrating a bug in GeoViewController.IdentifyLayersAsync() for FeatureCollectionLayer

Setup:

• Esri.ArcGISRuntime.WPF 200.6
• Esri.ArcGISRuntime.Toolkit.WPF 200.6
• create a collection of Graphic => graphics
• add then into a FeatureCollection
• add the FeatureCollection to FeatureCollectionLayer
• add the FeatureCollectionLayer into Map.OperationalLayers
• run the app and click on the cluster of symbols in the middle of the map

Bug repro:

• in code behind, we have TheMapView_GeoViewTapped which calls IdentifyLayersAsync directly on the MapView object
• in VM, we have a GeoViewController and a handler method OnGeoViewTapped, which calls IdentifyLayersAsync on the GeoViewController
• in the output we can see the number of GeoElements returned from both methods
• the direct path MapView.IdentifyLayersAsync returns 100 GeoElements
• the path via the GeoViewController.IdentifyLayersAsync return only a single GeoElement
