IMO is the moment to write something in out official reference.
We should dedicate a section on : *How work with TransactionScope*

I have never found a problem because I'm opening the NH'session and begin,

have seen is about ppl who don't want use the NH's transaction... with which
reason ? so far I saw only "style" reason... for me the "style" is a matter
for FashionTV.
