Prompt User (ReadLine) if EXE Run Without Command Arguments

I have a basic subcommand structure App.

What I want is if the executable is run without parameters, I want the App to essentially ReadLine and allow the user to input the commands.

Is this possible with a flag perhaps?

See below for my basic App structure:

		public static int Main(string[] args)
		{
			var app = new CommandLineApplication();

			app.HelpOption(inherited: true);

			// Invite User
			app.Command("invite", inviteUserCmd =>
			{
				var tenantName = inviteUserCmd.Argument("username", "Users name.").IsRequired();

				inviteUserCmd.OnExecute(async () =>
				{
						// do work here
					});
			});

			// register user
			app.Command("register", registerUserCmd =>
			{
				registerUserCmd.OnExecute(async () =>
				{
						// do work here
					});
			});

			app.OnExecute(() =>
			{
				Console.WriteLine("Specify a command");
				app.ShowHelp();
				return 1;
			});

			return app.Execute(args);
		}

Hey Nate, I just implement something I call “interactive session” where you get into a loop collecting and executing commands and this can be used in case no args are pass to the app, like this:

    public static void Main(string[] args)
    {
        if(args.Length == 0)
            CommandLineApplication.ExecuteInteractive<Git>();
        else
        {
            // Regular execute call goes here
        }
    }

I create a PR for your consideration #159
