Console.writeline issue

Hi folks - I am struggling on the very basics of Visual Studio 2013 release 1 - Using C#

using System;

namespace trialfile
{
    public class SystemTrial
    {
        public static void Method1()
        {
            Console.WriteLine("Hello, World!");
        }
    }
}

The error message I get is "The name 'Console' does not exist in the current context". Can you advise please?

It gets very frustrating as VS seems to have an incredibly steep learning curve for basics.
