NHibernate in an ASP.NET MVC application

April 29, 2008 by ryan

I've recently become interested in using NHibernate for some of my data access. For the past year or so I have been using SubSonic for that, however, I'm trying to take a bit more of a domain driven approach on the project I'm currently messing around on. Although I've only been looking at it for a couple of days, one thing I'm having a little bit of trouble figuring out is where my ISession should be opened / closed in an ASP.NET MVC application. Currently, I'm doing this in the Controller but I'm not totally sure that is the right way to go...

        public ActionResult ViewProduct(string ID)

        {

            using (ISession session = SessionManager.GetCurrentSession())

            {

                SimpleProductRepository repo = new SimpleProductRepository(session);

                return RenderView("ViewProduct",

                    new SimpleProductRepository(session).GetByTitle(ID));

            }

        }

What is the best way to go about this? Also, should I be looking more at using a Unit of Work pattern to achieve this?

You want this to be transparent to your controller...

Use something like this

www.codeproject.com/.../...rnateBestPractices.aspx

or Jeffrey Palermo's HybridSessionBuilder w/ Session per request

palermo.googlecode.com/.../...nateSessionModule.cs

or Unit Of Work

rhino-tools.svn.sourceforge.net/.../...lication.cs

@Matt: Thank you for the links! I will have to play around w/ these options a little more but they look great -- I knew how I was using the session was less than ideal.
