Voici un exemple en utilisant Fluent NHibernate et SQLite:
using System.Data;
using System.IO;
using FluentNHibernate.Cfg;
using FluentNHibernate.Cfg.Db;
using FluentNHibernate.Mapping;
using NHibernate;
public class Priority

public virtual int Id { get; set; }

}
public class Feature
{
public virtual int Id { get; set; }
public virtual string Name { get; set; }
public virtual Priority Priority { get; set; }
}
public class PriorityMap : ClassMap<Priority>
{
public PriorityMap()
{

Id(x => x.Id, "PriorityID");
Map(x => x.Name, "PriorityName");
}
}
public class FeatureMap : ClassMap<Feature>
{

Id(x => x.Id, "FeatureID");
Map(x => x.Name, "FeatureName");
References<Priority>(x => x.Priority, "PriorityID");
}
}
