What's your context? Web app or Win app? Using an IoC container?
Just my two pence, here's what I've started doing (not sure if it's
the best, but it's been working <grin>).
ISessionFactory factory = fluentConfig.BuildSessionFactory();
ForRequestedType<ISessionFactory>().CacheBy(InstanceScope.Singleton)
.TheDefault.IsThis(factory);
ForRequestedType<ISession>().CacheBy(InstanceScope.Hybrid)
.TheDefault.Is.ConstructedBy(c =>
c.GetInstance<ISessionFactory>().OpenSession());
For Web apps, I prefer to stuff the ISession in the http items.
Creating a session is cheap and it'll only connect to the DB when it
needs to. So, creating a bunch and just throwing them away is fine.
For a Win app, think about doing things in a conversational manner.
Think about things in the scope of a business transaction. Open your
session at the start of that business transaction and then commit and
flush at the end.
