Easy way to debug command-line apps

Program.cs

private static int Main(string[] args)
{
#if DEBUG
    if (args.Any(a => a == "--debug"))
    {
        args = args.Where(a => a != "--debug").ToArray();
        Console.WriteLine($"Ready for debugger to attach. Process ID: {Process.GetCurrentProcess().Id}.");
        Console.WriteLine("Press ENTER to continue.");
        Console.ReadLine();
    }
#endif

    // The rest of the code...
}
