I'm not able to draw on an ImageView object. Everytime I use the DrawString
method - I get a exception every time.

Recreate - do this:
1. Create a new Monotouch solution
2. Hook up a view - add a UIImageView to this view
3. Create outlet for this view - let's say ImageOutlet
4. Use this line of code: this.ImageOutlet.DrawString("test",new
5. Compile & run

Code that causes problems:
            window.MakeKeyAndVisible ();
            RectangleF r = new RectangleF(0,0,100,100);
            this.ImageOutlet.DrawString("test",new RectangleF(0,0,10,10));
            UIImageView newImage = new UIImageView();;
            window.AddSubview (VIEW);
