20,901 PointsAt a loss for what needs to be done here.
Even looking at the documentation on MSDN I can't figure this out. Have no idea how to do what I'm being asked to do here. Re-watching the video doesn't help at all.
using System;
namespace Treehouse.CodeChallenges
{
public class Program
{
public Func<int, int> Square = delegate (int number)
{
return number * number;
};
}
}

You would end up with something like this:
SPOILER ALERT
public Action<int, Func<int, int>> DisplayResult = delegate (int result, Func<int, int> operation)
{
};

20,901 Pointshad the parenthesis in the wrong spot.
public Action<int, Func<int, int>> DisplayResult = delegate(int result, Func<int, int>) operation vs public Action<int, Func<int, int>> DisplayResult = delegate(int result, Func<int, int> operation)
and forgot the curly braces....been a long day.
Thanks for the help Steven

20,901 PointsThought it would show which challenge it was. Speaking of Challenge Task 2 of 3.
Create a public Action field named DisplayResult that takes an int parameter and a Func<int, int> parameter. Initialize it with an anonymous method delegate that takes an int result parameter, and a Func<int, int> named operation.
