Cannot find hibernate.cfg.xml file

Problem
As I startup IIS and run my asp .net program, it reported this error meesage to complain it cannot find hibernate.cfg.xml file:
2009-10-12 10:01:23,250 ERROR TCePolice.CaseList.Page_Load(D:\work\source\TCePolice\TCePolice\CaseList.ascx.cs:48) - NHibernate.Cfg.HibernateConfigException: An exception occurred during configuration of persistence layer. ---> System.IO.FileNotFoundException: 找不到檔案 'D:\work\source\TCePolice\TCePolice\bin\hibernate.cfg.xml'。

Solution
Edit hibernate.cfg.xml file's property, Copy to Output Directory, and set its value to Copy if newer.
