I ran into this as well, but I was able to work it out. Hopefully, it will resolve the issue for others that run into this as well.

Code when I received the error:

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

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

Error Game.cs(9,15): warning CS0219: The variable area' is assigned but its value is never used Map.cs(10,7): warning CS1717: Assignment made to same variable; did you mean to assign somethin g else? Map.cs(11,7): warning CS1717: Assignment made to same variable; did you mean to assign somethin g else? Map.cs(5,25): warning CS0649: FieldTreehouseDefense.Map.Width' is never assigned to, and will always have its default value 0' Map.cs(6,25): warning CS0649: FieldTreehouseDefense.Map.Height' is never assigned to, and wil l always have its default value `0'
Compilation succeeded - 5 warning(s)

Code to resolve the extra errors:

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

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