MapTool creates lots of exceptions

Vidar

I have a maptool where I just place a marker on a map. Nothing else, no other business logic.

The marker is placed fine, however - when you look at the debug the amount of exceptions thrown from ArcGIS.Dektop.Mapping.dll is concerning.

What is going on here, should this be happening?

 

Here is my simple code:

internal class FooTool : MapTool
{
    private IDisposable _graphic = null;

    public FooTool()
    {
        IsSketchTool = true;
        SketchType = SketchGeometryType.Point;
        SketchOutputMode = SketchOutputMode.Map;
    }

    protected override async Task<bool> OnSketchCompleteAsync(ArcGIS.Core.Geometry.Geometry geometry)
    {
        try
        {
            MapPoint mapPoint = (MapPoint)geometry;

            await QueuedTask.Run(() =>
            {
                var mapView = MapView.Active;
                //Show marker
                if (_graphic != null)
                {
                    _graphic.Dispose();
                }
                _graphic = mapView.AddOverlay(mapPoint, SymbolFactory.Instance.ConstructPointSymbol(ColorFactory.Instance.BlueRGB, 14, SimpleMarkerStyle.Pushpin).MakeSymbolReference());
            });
        }
        catch (ArgumentException ae)
        {
            ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show(ae.Message, "Tool error");
        }
        catch (Exception ex)
        {
            Log.Error(ex);
        }

        return true;
    }
}

Where do you begin with this sort of stuff?! I did the migration process, but who knows if its done it 100% right. It would seem it hasn't ported cleanly.  I really don't want to start remaking all over project again.
