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

        int area = map.Width * map.Height;
    }
}

}

I'm getting the error CS1520: Class, struct, or interface method must have a return type

Is the message possibly referring to another module? To facilitate analysis, make a snapshot of your workspace and post the link to it here.

My guess was right, that error was actually for line 8 of "Map.cs".

Constructor methods must have the same name as their class, but here the method name is given as "map" (with lower-case "m") instead of "Map" (with capital "M"). For that reason, it is not recognized as being a constructor; and other methods are required to have a declared return type.
