Well, not that bad...We are always in the same battle field : we are using Ntiered architecture using WCF and we don not use DTO or whatever you may call them. As all ORM what matter is the quality of the mapping and understanding the N+1 issues. Well I'm quite disapointed on the evict and lock methods which are a bit hazardeous, but it's still working. the same way, I 'd love one day to get some time to work on a "Collection.Update()" We are using fully detached object from NHibernate, and we have a translation layer which ensure communication between Business Objects and persistents objects. Change Tracking is done through Business Object. After a lot of test on ORM cache (not only nhibernate) we consider and realize that it was "to much" for a single layer. Then we use a specific cache; communicating with the entities. Well, well; it's noon, I've a lot of work to finish. See you.

Great job guys with NH2 release. Have been waiting for it for quite some time. Fred, please keep us posted how your experience goes with NH2. http://ayende.com/3551/nhibernate-2-0-final-is-out#comment24http://ayende.com/3551/nhibernate-2-0-final-is-out#comment24Thu, 18 Sep 2008 16:45:23 GMTHuge work guys. I'm very proud to announce that a huge project involving NHibernate 2.0 (sources checked in today!) as ORM is in development. It's a portfolio management system, including architecture and langage migration. Thank you for making our life easier ! After comparing with a lot of others ORM, we choose to trust a product supported by ten years of exeprience and developped by passionate developpers. cheers guys !!!!!!!!!! http://ayende.com/3551/nhibernate-2-0-final-is-out#comment23http://ayende.com/3551/nhibernate-2-0-final-is-out#comment23Tue, 16 Sep 2008 21:30:38 GMT@DonkeyKong Send an e-mail to JBoss; sure they have one maintainer for www.nhibernate.org. http://ayende.com/3551/nhibernate-2-0-final-is-out#comment22http://ayende.com/3551/nhibernate-2-0-final-is-out#comment22Thu, 04 Sep 2008 16:25:42 GMTThis is great, but why isn't this mentioned on hibernate.org? http://ayende.com/3551/nhibernate-2-0-final-is-out#comment21http://ayende.com/3551/nhibernate-2-0-final-is-out#comment21Thu, 04 Sep 2008 15:48:18 GMTThe benefit I am getting from this ORM layer is unbeleiveable. Simple words cannot express my feelings for all the all hard work and tremendous amount of effort being put into this NHIBERNATE project. Thanks a lot guys/gals Regards Shanthu http://ayende.com/3551/nhibernate-2-0-final-is-out#comment20http://ayende.com/3551/nhibernate-2-0-final-is-out#comment20Fri, 29 Aug 2008 21:18:28 GMTCarlos, Ayende has been blogging about NHibernate for about 2 years, if he had to explain what it was at the beginning of every blog, it would be seriously annoying. Try not to be extremely lazy and angry at the same time. http://ayende.com/3551/nhibernate-2-0-final-is-out#comment19http://ayende.com/3551/nhibernate-2-0-final-is-out#comment19Tue, 26 Aug 2008 02:18:45 GMTgreat, is nice to see progress in this framework. More than compatible, we have a number of features that Hibernate 3.2 doesn't have! Try this in Hibernate: //finds a list of People with the same 'Name' property ICriteria criteria = session.CreateCriteria(typeof(Person)); criteria.SetProjection(Projections.ProjectionList() .Add(Projections.Max("Id")) .Add(Projections.GroupProperty("Name"))) .Add(Restrictions.Gt(Projections.Count("Name"), 1)); IList results = criteria.List(); Sorry but just compatible is the correct word: Hibernate 3.2 from Reference Doc 15.7: List results = session.createCriteria(Cat.class) .setProjection( Projections.projectionList() .add( Projections.rowCount() ) .add( Projections.avg("weight") ) .add( Projections.max("weight") ) .add( Projections.groupProperty("color") ) ) .list(); http://ayende.com/3551/nhibernate-2-0-final-is-out#comment18http://ayende.com/3551/nhibernate-2-0-final-is-out#comment18Mon, 25 Aug 2008 21:26:11 GMTExcellent news, and great work guys, i used nHibernate 1.2 on a project around 8 months and "Loved It" ago but haven't had another opportunity.

Some level of knowledge is assumed when reading this blog.

Would the answer be "let NHibernate create the schema"? I am getting some flak at a customer because other tools are supposedly so much nicer since they have a fancy visual mapping tool or ... God, what is this obsession with visual tools? http://ayende.com/3551/nhibernate-2-0-final-is-out#comment8http://ayende.com/3551/nhibernate-2-0-final-is-out#comment8Sat, 23 Aug 2008 20:53:14 GMTThanks ayende for the greate news, now it's your time to start a cool series of posts about. :-D http://ayende.com/3551/nhibernate-2-0-final-is-out#comment7http://ayende.com/3551/nhibernate-2-0-final-is-out#comment7Sat, 23 Aug 2008 19:42:41 GMTLooking forward to start working with this in projects.
