C# Objects. Using Static Methods. DistanceTo() method returning strange value. -2147483648

Question

I'm not sure where my code differs from the instructor.
// Point.cs
using System;
namespace TreehouseDefense
{
    class Point
    {
        public readonly int X;
        public readonly int Y;
    public Point(int x, int y)
    {
        X = x;
        Y = y;
    }

public int DistanceTo(int x, int y)
    {
        int xDiff = X - x;
        int yDiff = Y - Y;

int xDiffSquared = xDiff + xDiff;
        int yDiffSquared = yDiff + yDiff;

return (int)Math.Sqrt(xDiffSquared + yDiffSquared);

}
}
}
// Game.cs
using System;
namespace TreehouseDefense
{
    class Game
    {
        public static void Main()
        {
            Map map = new Map(8, 5);
        Point point = new Point(4, 2);

Console.WriteLine(point.DistanceTo(5, 5));
    }
}
}

Adding a value to itself doubles the value, it does not square it.  Did you perhaps intend to use the * symbol instead of +?
And for future postings, always include a link to the course page you are working with (or use the "get help" button which adds one for you).
Also, use Markdown formatting (https://teamtreehouse.com/library/code) to preserve posted code's appearance and retain special symbols.  An even better way to share code and make your issue easy to replicate is to make a snapshot (https://teamtreehouse.com/library/previews-and-snapshots) of your workspace and post the link to it here.
