当我使用“FluentNHibernate”时，出现错误。 .xml中的类似文件正常工作，但我想使用“FluentNHibernate”更容易。你知道我犯错的地方吗？以及如何解决这个问题？使用FluentNHibernate进行错误映射NHibernate 3.3

真的，我有问题，改变与配置。我将我的项目添加到这篇文章。告诉我我犯了什么错误以及如何解决这个问题。我没有找到这方面的好例子，可能这个项目将在未来完成时进入YouTube。对于其他用户。
如果您了解本文中的所有文件，则不必上传我的项目。
重要文件：
控制器 - >有控制器 模型，ModelsHelper，库和视图。如果你打开网站，我的软件必须在那里向数据库添加新的表格和数据。现在我遇到了问题。当我使用.xml文件时，一切正常，但我想使用“FluentNHibernate”，这是一个问题。

您没有配置任何自动映射，但是您正在使用自动映射覆盖。您需要修复您的配置。开始[这里]（https://github.com/jagregory/fluent-nhibernate/wiki/Getting-started）了解Fluent NHibernate的一般性介绍。并继续[这里]（https://github.com/jagregory/fluent-nhibernate/wiki/Fluent-configuration）了解如何配置它。 – 2013-02-26 11:38:56
