Description of Problem:

this should work:
    public partial class MapWithOverlayScreen : UIViewController
        MKCircle _circleOverlay = null;
        MKCircleView _circleView = null;
        public override void ViewDidLoad ()
            //---- add an overlay with the coords and a .3 radius
            this._circleOverlay = MKCircle.Circle(coords, .5);

            //---- set our delegate.
            //this.mapMain.Delegate = new MapDelegate();
            this.mapMain.GetViewForOverlay += (m, o) => {
                if(this._circleView == null)
                    this._circleView = new MKCircleView(this._circleOverlay);
                    this._circleView.FillColor = UIColor.LightGray;
                return this._circleView;

but the GetViewForOverlay delegate is never called, therefor no overlay shows

never gets hit.
