Cascade Saves with Fluent NHibernate AutoMapping - Old Answer Still Valid?

Question

I want to do exactly what this question asks: Cascade Saves with Fluent NHibernate AutoMapping

Using Fluent Nhibernate Mappings to turn on \"cascade\" globally once

Answer 1

Here's a full working example similar to the Getting Started guide https://github.com/jagregory/fluent-nhibernate/wiki/Getting-started

    namespace App4
    {
        class Program
        {
            static void Main(string[] args)
            {
                // create our NHibernate session factory
                var sessionFactory = CreateSessionFactory();

                using (var session = sessionFactory.OpenSession())
                {
                    // populate the database
                    using (var transaction = session.BeginTransaction())
                    {
                        // create a couple of Stores each with some Products and Employees
                        var topShelf = new Shelf();
                        var sw = new Stopwatch();
                        sw.Start();
                        for (var i = 0; i < 1000; i++)
                        {
                            var potatoes = new Product { Name = "Potatoes" + i.ToString(), Price = 3.60 + i };
