Name	Description
Attach(GeoView?)	Attaches a geoview to the controller, or detaches if `null`.
DismissCallout()	Dismisses a callout if it's open.
GetCurrentViewpoint(ViewpointType)	Gets the current Viewpoint of the GeoView.
IdentifyGraphicsOverlayAsync(GraphicsOverlay, Point, double, bool, long)	Identifies a limited number of graphics in all graphics overlays, at the given screen point.
IdentifyGraphicsOverlaysAsync(Point, double, bool, long)	Identifies a limited number of graphics in all graphics overlays, at the given screen point.
IdentifyLayerAsync(Layer, Point, double, bool, CancellationToken)	Initiates an identify operation on the specified layer which will return the single visible topmost geolement only.
IdentifyLayersAsync(Point, double, bool, CancellationToken)	Initiates an identify operation on all layers in the view which will return the single visible topmost geoelement per layer only.
OnGeoViewAttached(GeoView)	Raised when the GeoViewController has been attached to a GeoView.
