I don't know what's wrong with code Did you initialize the field 'numSides' to 4 in the base constructor?

what is the wrong with my solution ?

Polygon.cs
namespace Treehouse.CodeChallenges
{
    class Polygon
    {
        public readonly int NumSides;

        public Polygon(int numSides)
        {
            NumSides = numSides;
        }
    }

    class Square : Polygon
    {
        public readonly int SideLength;

        public Square(int sideLength) : base(int NumSides)
        {
            NumSides = 4;
            SideLength = sideLength;
        }
    }
}

Nice work so far Mohamed Reda ! You'll just have to pass the value in to the base class instead of defining it in the constructor in the way you have.

public Square(int sideLength) : base(*value to set numSides goes here*)
