C# NHibernate.MappingException导入Visual Studio 2012时发生异常

我有一个实现NHibernate的项目，该项目在我的机器上运行良好，带有Visual Studio 2010。当我将该项目导入Visual Studio 2012时，我遇到了NHibernate.MappingException

对于所有.hbm.xml文件，.hbm.xml被设置为嵌入式资源，而copy to output目录被设置为copy always

该项目在VS 2010下运行，因此我不确定如何解决这个问题。

包含所有所需信息的内部异常如下：

错误：NHibernate.MappingException:无法编译映射 文档：hibernateeexample.Domain.Dairy.hbm.xml--> NHibernate.MappingException:持久类 HibernateExample.Domain.Dairy，未找到HibernateExample---> System.TypeLoadException:无法加载类型 'HibernateExample.Domain.Dairy'来自程序集'HibernateExample， 版本=1.0.0.0，区域性=中性，PublicKeyToken=null'

在工厂配置期间，NHibernate读取所有嵌入的资源，包括第三个（从问题的顶部）：

因此，问题很清楚。没有可用的

hibernateeexample.Domain.Dairy

类（未部署、输入错误或名称空间不正确）。好消息或消息是您的映射已被找到并解析

---

尝试确保应用程序能够访问映射的类

映射异常说明了什么？@SimonWhitehead，我在新编辑中添加了上面的堆栈跟踪。您的

Dairy

类是否在

NHibernateeExample.Domain

命名空间中定义？@SimonWhitehead，程序集是HibernateExample，因此它是在HibernateExample.Domain命名空间中定义的。如果映射文档作为资源嵌入，通常不应将它们复制到输出目录。我已检查并重新检查了命名空间，为什么它会在VS 2010中工作而不是VS 2012中工作，而且根本没有对代码进行任何更改？看起来您缺少引用。异常非常简单：映射的内容无法（通过反射）找到<代码>持久类HibernateExample.Domain.Dairy，HibernateExample未找到意味着，在应用程序域（通常位于bin中的dll）中没有Phill建议的类，缺少引用可能是“部署”跳过的原因。因此，我们需要的（不是引用本身），而是“POCO实体”程序集已真正部署，并可在应用程序域中使用
