In MapViewBehavior.cs, add a using statement to Esri.ArcGISRuntime.Layers, and then add a new MapViewTapped event handler to the OnAttached method, like this:AssociatedObject.MapViewTapped += AssociatedObject_MapViewTapped;

In AssociatedObject_MapViewTapped, add the following code:MapView mapView = sender as MapView; OverlayItemsControl overlays = mapView.Overlays; OverlayItemsCollection collection = overlays.Items; System.Windows.Controls.Border overlayControl = (System.Windows.Controls.Border)collection[0]; // get the location tapped on the map var mapPoint = e.Location; // Get possible features and if none found, move to next layer FeatureLayer featureLayer = (FeatureLayer)mapView.Map.Layers[1]; // Get possible features and if none found, move to next layer var foundFeatures = await featureLayer.HitTestAsync(mapView, new Rect(e.Position, new Size(10, 10)), 1); if (foundFeatures.Count() == 0) return; var feature = await featureLayer.FeatureTable.QueryAsync(foundFeatures[0]); overlayControl.DataContext = feature.Attributes; Esri.ArcGISRuntime.Controls.MapView.SetViewOverlayAnchor( overlayControl, mapPoint); overlayControl.Visibility = Visibility.Visible;;
