Just put the word "public" at the beginning of a declaration.

Here's a link to the definition of Func in the Microsoft documentation. You can see the instructor looking it up at about 2:45 in the video.

using System;

namespace Treehouse.CodeChallenges { public class Program { //public delegate int Func<in int, out int> Square (int number); //public delegate int Func<in int,out int>(int number); //public delegate string Square(int number);

    public Func<int, int> Square(int number);

    static void Main(string[] args)
    {
        Square = delegate(int number) 
        {
            return number*number;
        }
    }
}

}

Still doesn't work. (none of the ways I tried to declare it)
