How to integrate c# help into console application

Question

Background Information (based on my first question): i want to integrate in my "GUI.exe" (written in c#) a help function. Then when i want to start in my cmd -> "GUI.exe --h" the help function.

Tried a stackoverflow- post: I have try to use this solution: Adding "--help" parameter to C# console application.

static bool ShowHelpRequired(IEnumerable<string> args)
{
    return args.Select(s => s.ToLowerInvariant())
        .Intersect(new[] { "help", "/?", "--help", "-help", "-h" }).Any();
}

Current problem:

I don't know where I can integrate the help function. I don't know whether a particular setting in my Microsoft Visual Studio must configure.

In advance thank you for your Support.

Call ShowHelpRequired in your main method :

    static void Main(string[] args)
    {

        if(ShowHelpRequired(args))
        {
            Console.WriteLine("Show help message here");
        }
    }
