Hi, I'm trying to convert my data layer from Linq2Sql to nHibernate. I think Xml the configuration in nHibernate is pretty backwards so I'm using Fluent.

I have a legacy DB which uses a guid to map children to the parent entity. In my domain layer, I'd prefer to obscure this quirk, so I'd like to have my parent entity look like this: public class Parent { virtual public int Id {get; protected set; } virtual public string ParentContent { get; set; } virtual public Guid Refer...
