isOnMap variables not printing to the console

The files compile properly, and the file executes without crashing (as far as I can tell), but its not printing the True and False statements to the command line.

I feel I haven't properly defined isOnMap, but can't find any errors when I compare it to the code in the video.

Game.cs:

using System;

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

          Point point = new Point(4, 2);
          bool isOnMap = map.OnMap(point);
          Console.WriteLine(isOnMap);

          point = new Point (8, 5);
          isOnMap = map.OnMap(point);
          Console.WriteLine(isOnMap);
        }
    }
}

Map.cs

namespace TreehouseDefense
{
  class Map
  {
     public readonly int Width;
     public readonly int Height;

    public Map(int width, int height)
    {
      Width = width;
      Height = height;
    }


    public bool OnMap(Point point)
    {

      return point.X >= 0 && point.X < Width && 
             point.Y >= 0 && point.Y < Height;

    }

  }

Your code is apparently right, don't forget to save all the files before runing the program.

Hello! Had the same issue, everything was right, but still didn't printed. I checked if console commands were right.

You should use mcs -out:TreehouseDefense.exe *.cs && mono TreehouseDefense.exe I just missed first .exe when tried to compile & run.

Hope this helps.

As dasgk said, In the console you have to run like this

mcs -out:TreehouseDefense.exe *.cs && mono TreehouseDefense.exe
