What would be the best practice for managing transactions Fabio?
Initially, I had my Repositories handling their own transactions. Like
so:
*
public class DeviceRepository : IRepositoryDevice
{
private IDataSource _db;
the answer is too long.you will discover it by your self when you will need
two save in the same transaction or/and when you will have 2 opened forms
needing 2 different business transactions.

Follow up, in case anyone else stumbles on this thread:
I managed to get something simple working and am fairly happy with the
result, but would like to vet the idea against the community to make
sure I'm not doing something horribly wrong.
What I ended up doing was writing an IUnitOfWork
And he need to manage transactions too...I hoping he don't want begin
a transaction at UoW start.
After that I would see the code where the UoW is used...

Even if your articles are very clear and the samples in nhaddins are
very good, reading them was not enough for me to understand them.
And it took me a lots of efforts to understand where is the CpBt in
the samples.
Really thanks for this

A much better approach would be to tailor your HQLs (or
criteria queries) to each use case and select exactly the data you
need to touch explicitly

Wojciech,
Thank you sir. This is incredibly helpful. I had no idea this
capability for contextual sessions existed in NHibernate. I believe
this is going to help me tremendously.
Awesome post Wojciech.

The attitude that will help you is the* reader attitude*. No one
has enough time to write something twice.
You should be reading the former links and then answer concrete questions.

it. But you have enough time to

Blevasis,
This is a great explanation of the way you're doing it. But again, I
don't understand it. Specifically, I don't understand the details of
how it is implemented.

usecase may instantiate it's own
