With the Actions and Funcs code challenge I am always getting the message "Did you return the result of 'number * number' in your anonymous method delegate?". However I am always returning a result from my anonymous method. Any guidence would be greatly appreciated!
using System;
namespace Treehouse.CodeChallenges
{
public class Program
{
public Func<int, int> Square = delegate(int number)
{
int square = number * number;
return square;
}
}
}

While using an intermediate variable between the calculation and return would certainly work in practice, the challenge doesn't want it done that way here.
Also, you need a semicolon at the end of the delegate definition because it's part of an assignment statement.

10,068 PointsHi Steven
Many thanks, I guess that is the most efficient way to do it so I can see why they ask for it done that way. Also thanks for pointing out the semi colon, easy to miss. :)

231,198 PointsIt doesn't seem right for a challenge to fail just for not being "most efficient". You might want to report that as a bug to Support.
