MappingException未被处理: NHibernate

Question

我正在尝试从“NHibernate”( NHibernate在行动中 )一书中了解有关NHibernate在行动中的信息，并试图编译和运行第一个示例，这给了我以下例外：

无法编译映射文档： Namespace.FolderName.ClassName.hbm.xml

内在的例外是

{"<hibernate-mapping xmlns='urn:hibernate-mapping-2.2'> was not expected."}

这是我的映射文件：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:hibernate-mapping-2.2"
                   auto-import="true">
  <class name="Namespace.Folder.ClassName,Namespace.Folder" lazy="false">
    <id name="id" access="field">
      <generator class="native" />
    </id>
    <property name="name" access="field" column="name"/>
    <many-to-one access="field" name="manager" column="manager"
                 cascade="all"/>
    </class>
</hibernate-mapping>

当我试图创建如下会话时，就会发生这种情况：

static ISession OpenSession()
        {
            if (factory == null)
            {
                Configuration c = new Configuration();
                c.AddAssembly(Assembly.GetCallingAssembly());
                factory = c.BuildSessionFactory();
            }
            return factory.OpenSession();
        }

异常由以下行引发：

c.AddAssembly(Assembly.GetCallingAssembly());

下面是整个异常堆栈跟踪：

有人能给我一些关于这里发生了什么的建议吗？

谢谢

确保映射文件的构建操作设置为“嵌入式资源”。

编辑：

试一试

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" auto-import="true">

注意nhibernate中的n。
