Transaction support is available too, but it's not automatically "one transaction per request". I think a good place for

问题 I'm currently using NHibernate 3.1 in a ASP.Net application and got it working pretty well (with Fluent). I managed to make it log all generated SQL queries to my output tab while debugging by using the following snippet in Application_Start: private static DebugTextWriter _writer; protected virtual void Application_Start(object sender, EventArgs e) { _writer = new DebugTextWriter(); Console.SetOut(_writer); } I recently upgraded NHibernate from 2.1 to 3.1 and now my update and delete
