Here are my 5 cents!
I have this on my web.config:
<property
name="current_session_context_class">NHibernate.Context.WebSessionContext,
NHibernate</property>
You can't use managed web or any other context, they won't work properly.
On the Application_Start method I create an ISessionFactory and I register
it on my IoC container so that it is available anywhere through the Common
Service Locator.
Then on the Application_BeginRequest method I have something like this:
if (this.NeedsProcessing == true) //check if the request is for dynamic
content, for example, not images, scripts, css, etc
{
ISession session =
ServiceLocator.Current.GetInstance<ISessionFactory>().OpenSession();
session.BeginTransaction();
WebSessionContext.Bind(session);
}
Next, my Application_EndRequest has this:
if (this.NeedsProcessing == true)
{
ISessionFactory factory =
ServiceLocator.Current.GetInstance<ISessionFactory>();
ISession session = WebSessionContext.Unbind(factory);
if (session != null)
{
if ((session.Transaction != null) && (session.Transaction.IsActive == true)
&& (session.Transaction.WasCommitted == false) &&
(session.Transaction.WasRolledBack == false))
{
session.Transaction.Commit();
session.Transaction.Dispose();
}
session.Dispose();
}
}
And finally, most people forget about Application_Error, if there is an
error, Application_EndRequest is not called:
ISessionFactory factory =
ServiceLocator.Current.GetInstance<ISessionFactory>();
ISession session = WebSessionContext.Unbind(factory);
if (session != null)
{
if ((session.Transaction != null) && (session.Transaction.IsActive == true)
&& (session.Transaction.WasCommitted == false) &&
(session.Transaction.WasRolledBack == false))
{
session.Transaction.Rollback();
session.Transaction.Dispose();
}
session.Dispose();
}
