Здравствуйте, я новичок в nhibernate и пытаюсь создать менеджер сеансов для веб-приложения, который позволит мне использовать его при вызове нового клиента.Думаю, я нашел менеджер сеансов, который мне пригодится, но я не знаю, как его запустить в своем веб-API, потому что он просто дает код и не реализует его.Кто-нибудь может мне помочь?
