I don't have more ideas for resolve this problem...
My configuration is in app.config, and i put only one mapping for my test in code.
Configuration cfg = new Configuration().Configure();
cfg.AddFile("MyTable.hbm.xml");
ISessionFactory factory = cfg.BuildSessionFactory();//Error here
Thanks in advanced for any help.
