Using dictionaries as entities

A little-known feature of NHibernate is EntityMode.Map. In this recipe, I'll show you how we can use this feature to persist entities without classes.

2. Add a new class named Recipe to the folder:

          new Dictionary<string, object>() {
            {"Actor...
