My advice is to read through (N)Hibernate in Action in tandem with the
documentation to get a good feel of the main components of NHibernate. I
would still read through the best practices Tuna recommended on codeproject
(http://www.codeproject.com/KB/architecture/NHibernateBestPractices.aspx).
Now that we have Burrow (http://nhforge.org/wikis/burrow/default.aspx), I
would definitely look into that, because it addresses session and
transaction management, which is likely to be the next hurdle you'll want to
cross, all with minimal effort on your part.
Burrow, burrow, burrow.
Hope this helps,
David
The link Tuna gave you will show u best practices for managing a session by
hand.
