About NHibernate's ISession

Question

In this question, the user asks the better way to close sessions because he was having some errors.

The most voted answer is Ayende's answer that says:

You should always use session.Dispose(); The other are for very strange occurances

Should I really always call session.Dispose()? Isn't enough to call session.Close()?

Answer 1

Rule of thumb in .net is "if class is IDisposable always call Dispose", but better use using

Answer 2

Session Dispose() does a couple more things than just Close()ing, so yes, always use Dispose()
