Challenge Task 1 of 3 In the Program class, declare a public Func field named Square that takes an int and returns an int. Use an anonymous method to assign a delegate that takes an int parameter named number and returns the result of number * number.

You forgot to end your delegate assignment with a semicolon.

Also, the "check work" seems to have it's own ideas about syntax. It seems to want a space between the int specs of the Func, and it also wants spaces around the multiply operator.

        public Func<int, int> Square = delegate (int number)
        {return  number * number;};

You might want to report the space issue as a bug to Support, it might even get you a "special Exterminator badge".
