Why doesn't Console.Write(x is MapLocation) print whether it's true or false in my code?

It's seemingly identical to the instructors code but it as well as the 2 following Console.WriteLines don't indicate True or False:

using System;

namespace TreehouseDefense { class Game { public static void Main() { Map map = new Map(8, 5);

      Point x = new MapLocation(4, 2);

      Point p = x;

      map.OnMap(new MapLocation(0, 0));

      Console.WriteLine(x.DistanceTo(5, 5));

      Console.WriteLine(x is MapLocation);
      Console.WriteLine(x is Point);

      Point point = new Point(0, 0);
      Console.WriteLine(point is MapLocation); 
    }
}

}

Just a guess, but perhaps your last compile (after adding these lines) was not successful, so you're running an older version of the executable. Also be sure you saved your changes in the editor before re-compiling.

To allow a more thorough analysis and accurate answer, make a snapshot of your workspace and post the link to it.
