public Square(double sideLength) : base(4) => SideLength = sideLength;
public void Scale(double factor) => SideLength *= factor;
}
}

public double SideLength => get; private set; <- don't do this. Keep it with the braces.
This is the constructor and not a normal method. You can tell because it has no return type. Don't try to shorten it. Remove the => and add back the braces.
public Square(double sideLength) : base(4) => SideLength = sideLength;

public double Area => SideLength * SideLength;

SQUARE.CS
namespace Treehouse.CodeChallenges { class Square : Polygon { public double SideLength { get; private set; }
}
POLYGON.CS
namespace Treehouse.CodeChallenges { class Square : Polygon { public double SideLength { get; private set; }
}
What am i missing now?
