Properties for your entities i.e. database fields should be public virtual. Also try specifying the assembly of a mapping class instead of using GetExecutingAssembly(), I do vaguely recall experiencing trouble with it when I tried setting up FNH for the fir

I uploaded the source code to github for in case someone want to see the complete code. In no persister for a nutshell it's 3 projects. One "infrastructure" (domain entities and service interfaces), nl. krok.blog and a nHibernate implementation of those services in krok.blog.data. I "use" this in a sandbox console app (in the test folder). The domain are very simple (maybe not for a n00b with nHibernate) but let me post some code: namespace krok.blog.Domain { public class Post : Entity { public Post() { Categories = new List(); Comments = new List(); } public virtual string Title { get; set; } public virtual string Body { get; set; } public virtual string Synopsis { get; set; } public virtual IList Categories { get; set; } public virtual IList Comments { get; set; } } } Mapping namespace krok.blog.data.Mappings { public class PostMap : ClassMap { public PostMap() { Id(x => x.Id); Map(x => x.Title); Map(x => x.Body); Map(x => x.Synopsis); HasMany(x => x.Comments).KeyColumn("CommentId"); HasManyToMany(x => x.Categories) .Table("BlogPostsCategories") .ParentKeyColumn("PostId") .ChildKeyColumn("CategoryId"); Table("BlogPosts"); } } } Configuration: private static void InitializeSessionFactory() { string connectionString = ConfigurationManager.ConnectionStrings["blogdb"].ConnectionString; _sessionFactory = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2008.ConnectionString(@connectionString).ShowSql()) .Mappings(m => m.FluentMappings.AddFromAssemblyOf()) .BuildSessionFactory(); } I'll keep trying to figure it out and will post the solution *IF* I ca
