Comments on: What NHibernate Related Topics Would You Like To Read About? http://davybrion.com/blog/2008/10/what-nhibernate-related-topics-would-you-like-to-read-about/ Trying to walk that thin line between intelligence and ignorance Thu, 29 Jul 2010 21:01:23 +0000 hourly 1 http://wordpress.org/?v=3.0 By: Davy Brion http://davybrion.com/blog/2008/10/what-nhibernate-related-topics-would-you-like-to-read-about/comment-page-1/#comment-3838 Davy Brion Mon, 20 Oct 2008 11:25:57 +0000 http://davybrion.com/blog/?p=513#comment-3838 heh... a lot of .NET developers don't really seem to be able to distinguish between LINQ (the language feature) and LINQ To SQL or Entity Framework either :) But i probably won't compare NHibernate to either of them... i have zero interest in LINQ To Sql because i think it will ultimately be neglected (or even dropped) by Microsoft to increase adoption of Entity Framework, and Entity Framework is probably a version or 2 removed from being an option worth considering. heh… a lot of .NET developers don’t really seem to be able to distinguish between LINQ (the language feature) and LINQ To SQL or Entity Framework either :)

Admittedly I haven't read up on Linq yet (Java guy speaking ;-)), I expected it to be Microsoft's ORM-like solution for persistence. I see.

you probably meant LINQ To SQL, or Entity Framework :)

As far as I know, these are two top choices for persistence layer technologies in .NET apps (not taking ADO.NET into account)? I'm also quite interested in a discussion regarding stateless sessions. Especially the why, not the what ;-) A comparison that interests me is Linq vs. NHibernate.

You just need to define parameterized filters in the mapping and enable the filter when opening the session: session.EnableFilter(filterName).SetParameter(name, value) - Custom Property Accessors : custom implementations of IPropertyAccessor / IGetter / ISetter interfaces. Very usefull when you need to map completely different data structures (Entity / Database), when dealing with a legacy database and a redesigned domain model for example. You just need to reference your custom property accessor in the 'access' tag of the mapping files (property / relation / ...). - ‘Dynamic’ Filters : http://www.hibernate.org/hib_docs/nhibernate/1.2/reference/en/html/filters.html

If you mean dynamic criteria, there are a lot of examples for that already available @Steve
