有没有办法用NHibernate返回插入记录的主键？

using NHibernate;
using NHibernate.Cfg;
using NHibernate.Dialect;
using NHibernate.Driver;
using NHibernate.Mapping.ByCode;
using NHibernate.Tool.hbm2ddl;
using System;

namespace NHibernateExample
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var configuration = new Configuration();
            configuration.DataBaseIntegration(db =>
            {
                db.ConnectionString = "Server=localhost;Database=test;User Id=root;Password=password;";
                db.Driver<MySqlDataDriver>();
                db.Dialect<MySQL5Dialect>();
            });

            var mapper = new ModelMapper();
            mapper.AddMapping<UserMap>();
            var mapping = mapper.CompileMappingForAllExplicitlyAddedEntities();
            configuration.AddMapping(mapping);

            var sessionFactory = configuration.BuildSessionFactory();
            var session = sessionFactory.OpenSession();

            var user = new User
            {
                Name = "John Doe",
                Email = "john.doe@example.com"
            };

            using (var transaction = session.BeginTransaction())
            {
                var id = session.Save(user);
                transaction.Commit();

                Console.WriteLine($"Inserted record with ID: {id}");
            }
        }
    }
}
