I'm hosting the WPF control in a WinForms project. I currently have a label positioned over the map for informational messages, such as 'drawing map' or 'no data selected'. However when the map is resized or panned, the label and/or the map are drawn incorrectly, or not at all. Is there a built-in overlay available in the map that is fixed to screen coordinates, rather than geographic coordinates? Similar to how the mouse position and scale never move.
