Hi Jason,
Thank you for your reply. That is not harsh at all. I am well aware of
the mistake I made. I was so frustrated with linq, that
I just had to drop it and quickly replace it with something else. Even
without any previous experience with NHibernate/AR,
it seemed far more intuitive and capable than Linq, and I decided to use
it. Even with the problems I have, I don't regret one bit.
I read just about everything I could find on the web about AR/NH session
management, but most of it is talking about web apps.
Also, a lot of it is just adding to my confusion. For example, some
people say using one session for application is a 'time bomb',
other people ('Hibernate in Action', IIRC) say it is just the right
way... Another example. I found many articles suggesting Session.Clear()
should be called after Session.Flush(), but then I find Ayende's '...if
you're calling Clear(), you're doing something weird...'
If something I wrote sounds rude or in any way inappropriate, my apologies.
Again, thanks for your reply. Downloading nhprof it right away.
