public class Calculator
{
    public void Add(int value1, int value2)
    {
        Console.WriteLine($"Answer:  {value1 + value2}");
    }

    public void Subtract(int value1, int value2)
    {
        Console.WriteLine($"Answer:  {value1 - value2}");
    }
}

class Program
{
    static int Main(string[] args)
    {
        return new AppRunner<Calculator>().Run(args);
    }
}

With these two classes, we've defined an Add and Subtract command and help is automatically generated.
