My understanding is that EF have no auto-flush at all, and that EF.SaveChanges() will internally create a TransactionScope that it will call Complete() on before returning. This will mean that the changes are committed, UNLESS the call to EF.SaveChanges() is performed within an already open ambient transaction, in which case you will still have to call Complete() on that yourself, per the normal workings of TransactionScope. Using EF.SaveChanges() without an ambient transaction would, as I understand it¸ make you preceding reads happen in different transactions from the write operation.
So I don't really see a difference in the number of calls. Note that you normally don't have to call Flush(), because it will normally happen automatically when committing. /Oskar 2012/9/19 Mouhong Lin <[email protected]> > But I think Flush is not 100% same as transaction.Commit(), right? > In EF, Linq 2 SQL, Rave nDB etc, session.SaveChanges() equals to > transaction.Commit() in NHibernate. > I think it's more convenient to have a method like SaveChanges directly in > the ISession interface. > But NHibernate doesn't have such a method.
