嵌套的NHibernateFacility SessionManager.OpenSession调用

Question

我觉得我误解了一些东西。请查看以下代码。我设置了DefaultSessionLifeStyleOption.SessionPerTransaction，但我的会话有不同的会话ID，即使它们在同一个交易中。我期待一个会议，但有两个会议。

我做错了什么，我该怎么做才能做到我想要的？我是否应该将ISession注入Program并让我的方法使用该会话？但后来我没有失去SessionManager与AutoTxFacility的好处？

                .AddFacility<AutoTxFacility>()            // automatically manages DB transactions for us, if we want.
