I’m simply trying to change the color of the map background. I’ve done this in the WinForms version fine.

```
private void Map_Loaded(object sender, RoutedEventArgs e)
{
    Map.MapUnit = GeographyUnit.DecimalDegree;
    Map.MapResizeMode = ThinkGeo.MapSuite.Shapes.MapResizeMode.PreserveScaleAndCenter;
    BackgroundOverlay backgroundOverlay = new BackgroundOverlay();
    backgroundOverlay.BackgroundBrush = new GeoSolidBrush(GeoColor.GeographicColors.DeepOcean);
    Map.BackgroundOverlay = backgroundOverlay;
    Map.Refresh();
}

```

The map stays white, but looking at the watchlist, it shows the backgroundbrush set to the correct color. I have the same exact code in the winforms version and it works. What could the issue be?

Hi Dan,

Thanks to let us know it, I tested it and also found the BackgroundOverlay don’t works in the latest version, I have let our developer know it and it will be solved after they back from vacation next week.

You can use the code as below instead of BackgroundOverlay:

```
map.Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Colors.LightBlue);

```

Wish that’s helpful.
