copied!<p>I agree, there aren't many examples for stateful apps. I'm thinking of doing the following:</p> <p>Like you I have a windows service hosting a number of WCF services. So the WCF services are the entry points. Ultimately all my WCF services inherit from AbstractService - which handles a lot of logging and basic DB inserts/updates.</p> <p>In one of the best NHibernate posts I've seen, a HttpModule does the following: see <a href="http://www.codeproject.com/KB/architecture/NHibernateBestPractices.aspx" rel="nofollow noreferrer">http://www.codeproject.com/KB/architecture/NHibernateBestPractices.aspx</a></p> <pre><code>private void BeginTransaction(object sender, EventArgs e) { NHibernateSessionManager.Instance.BeginTransaction(); } private void CommitAndCloseSession(object sender, EventArgs e) { try { NHibernateSessionManager.Instance.CommitTransaction(); } finally { NHibernateSessionManager.Instance.CloseSession(); } } </code></pre> <hr> <p>So perhaps I should do something similar in AbstractService. So effectively I'll end up with a session per service invocation. If you examine the NHib best practices article link above, you'll see that the NHibernateSessionManager should deal with everything else, as long as I open and close the session (AbstractService constructor and destructor).</p> <p>Just a thought. But I'm experiencing errors because my session seems to be hanging around for too long, and I'm getting the infamous error - NHibernate.AssertionFailure: null id in entry (don't flush the Session after an exception occurs).</p>

Querying!
