One can read in the NHibernate manual:



Now, my question is as in the topic: what is the ISession exception exactly? How do I distinguish it from other NHibernate exceptions that probably do not need session dismission.

For example if I catch NHibernate.ADOException do I have to close the current session or can I just handle this exception according to my needs and keep on doing my job without closing everything?

Thanks in advance,
Marcin

There is no such thing as "the ISession exception". If a session throws any exception (including ADOException), you should close and discard it.

That wasn't clear for me. Now it is. Thank you.

Case closed as for me.
