Is there a way to return the primary key of inserted record with NHibernate?

Question

Well, the question kinda nails it down. I'm currently doing something like this:

using (var session = _sessionFactory.OpenSession())
{
     using (var transaction = session.BeginTransaction())
     {
         Car newCar = new Car();
         newCar.name = "Jeep";

         session.Save(newCar);
         transaction.Commit();    
     }
}

Answer 1

return newCar.Id;

After you've committed your transaction of course.
