So I do not need to make an explicit Update(someEntity) call?
using(var transactionScope = new TransactionScope())
using(var session = sessionFactory.OpenSession())
{
var someEntity = session.Get<SomeEntityType>(someId);
someEntity.Name = "bla";
session.Update(someEntity); // I want to avoid these explicit
Update-calls by tracking the (dirty) entities in a session and do a single
call to a "void SaveChanges()" method. The "SaveChanges" method should do
the updating on the entities in a session. I still want to explicitly insert
new entities with session.Save(newEntity), which I abstract and in a method
called "Store".
transactionScope.Complete();
}
