Thanks for your quick responses on this.
However I still don't understand why an NHibernate transaction is
required in addition to TransactionScope. I've written a test (below)
and TransactionScope works without the need to create an NHibernate
transaction.
The result is that Richard and Simon are saved to the database, but
Norman is rolled back.
What additional benefit do you get from also calling
"session.BeginTransaction()"?
public void TransactionScopeTest()
{
Person norman = new Person() { Name = "Norman" };
Person richard = new Person() { Name = "Richard" };
Person simon = new Person() { Name = "Simon" };
using (ISession s1 = OpenSession())
{
using (TransactionScope scope = new
TransactionScope())
{
s1.Save(norman);
// do not complete so automatically rollback
}
}
using (ISession s2 = OpenSession())
{
using (TransactionScope scope = new
TransactionScope())
{
s2.Save(richard);
scope.Complete();
}
}
using (ISession s3 = OpenSession())
{
s3.Save(simon);
}
}
