C#, basic error

So I am making a super basic (I'm in my second week of learning C# so please excuse my ignorance) program that takes a string input from a user and outputs the string backwards. I have copied the book to a T in regards to a majority of it but I have noticed spelling errors in some of their code so I don't have a lot of faith in what they are showing. My compiler is giving me an error with WriteLine and ReadLine and I don't understand why as the book says it works. This is the error I am getting;

"WriteLine does not exist in the current context" same with "ReadLine"

My code;

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication1
{
    static class funcStrings
    {

        public static string ReverseString(string s)
        {
            char[] arr = s.ToCharArray();
            Array.Reverse(arr);
            return new string(arr);
        }
    }

    class runProgram
    {

        class Program
        {
            static void Main()
            {
                string name;
                WriteLine("Enter your name to be reversed ");
                name = ReadLine();
                Console.WriteLine(funcStrings.ReverseString(name));
            }
        }
    }
}

Thanks for any guidance here

Currently it is:

static void Main()
 {
     string name;
     WriteLine("Enter your name to be reversed ");
     name = ReadLine();
     Console.WriteLine(funcStrings.ReverseString(name));
 }

You need to add a Console.WriteLine("Enter your name to be reversed"):

You can add such namespace:

using static System.Console;

This brings all the static members from the System.Console class into scope, so that you don't need to prefix them with Console. It is a C# 6 feature, and useful when accessing many members in a static class. See relevant documentation.

The problem is probably that it should be Console.WriteLine and Console.ReadLine.

You just need to add Console. in front:

            Console.WriteLine("Enter your name to be reversed ");
            name = Console.ReadLine();
