Use NHibernate to insert nearly 100,000 records into the database, as in the following example:ISession session = session. BeginTransaction (); for int i=0; i100000; i++ ) { new Customer (...); Session. Save (customer);} Tx.commit (); session. Close ();This will throw OutOfMemoryException and terminate at about 50 000 records. This is because nhibernate caches all newly inserted customer instances in the Session-level cache.When you persist a new object, you must constantly control the s
