NHibernate: ORM for .Net

NHibernate website states [1]: “NHibernate is a mature, open source object-relational mapper for the .NET framework. It’s actively developed , fully featured and used in thousands of successful projects.”

I found a demo project by Dario Quintana [4] and updated it, combining it with Getting Started  Guide – Your first NHibernate based application [2].

The demo app on the Getting Started  Guide – Your first NHibernate based application [2] is a little bit buggy, but combining it with Dario Quintana demo I got to understand this NHibernate stuff.

Sample project with full source code here:


Some code example:

public class Employee 
public virtual int Id { get; private set; } 
public virtual string FirstName { get; set; } 
public virtual string LastName { get; set; } 
public virtual Store Store { get; set; } 

You can notice the following:

  1. Firstly, the Id property has a private setter, this is because it’s only NHibernate that should be setting the value of that Id.
  2. Secondly, all the properties are marked virtual; this is because NHibernate creates “proxies” of your entities at run time to allow for lazy loading, and for it to do that it needs to be able to override the properties.
