New Post: Polygon with inner polygons

Oh, sorry, you have to change something more in GMapPolygon.cs:

Change

internal void UpdateGraphicsPath()

  {

...
}
to

public virtual void UpdateGraphicsPath()

  {

...
}

and

GraphicsPath graphicsPath;

to

protected GraphicsPath graphicsPath;


Then remove

private GraphicsPath graphicsPath = new GraphicsPath();

from the class GMapPolygonHole.cs

Then it should work!
