Hi Evan,
You can set the "Cursor" property of your custom tool to change the standard cursor.
internal class CustomMapTool : MapTool
{
public CustomMapTool()
{
IsSketchTool = true;
SketchType = SketchGeometryType.Rectangle;
SketchOutputMode = SketchOutputMode.Map;
var cursorEmbeddedResource = new Cursor(new MemoryStream(MapExploration.Resource1.red_cursor));
var systemCursor = System.Windows.Input.Cursors.ArrowCD;
Cursor = cursorEmbeddedResource;
Cursor = systemCursor;
}
....
