HibernateConfigException解析配置时发生异常

Question

我使用Nhibernate创建了控制台应用程序。
我创建hibernate.cfg.xml文件

<?xml version="1.0" encoding="utf-8" ?> 
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" 
         assembly="NHibernateDemo" 
         namespace="NHibernateDemo"> 
    <session-factory> 
     <property name="connection.connection_string_name">default</property> 
     <property name="connection.driver_class">Nhibernate.Driver.SqlClientDriver</property> 
     <property name="dialect">Nhibernate.Dialect.MsSql2008Dialect</property> 
     <mapping assembly ="NHibernateDemo" /> 
    </session-factory> 
</hibernate-configuration> 

，这是我的代码

using System; 
using System.Linq; 
using System.Reflection; 
using HibernatingRhinos.Profiler.Appender.NHibernate; 
using NHibernate.Cfg; 
using NHibernate.Dialect; 
using NHibernate.Driver; 
using NHibernate.Linq; 

namespace NHibernateDemo 
{ 
internal class Program 
{ 
    static void Main(string[] args) 
    { 
     NHibernateProfiler.Initialize(); 

     var cfg = new Configuration(); 
     cfg.Configure("hibernate.cfg.xml"); 
     var sessionFactory = cfg.BuildSessionFactory(); 

     int newId; 

     using (var session = sessionFactory.OpenSession()) 
     using (var tx = session.BeginTransaction()) 
     { 
      var newCustomer = CreateCustomer(); 
      Console.WriteLine("Before saving:"); 
      Console.WriteLine(newCustomer); 
      session.Save(newCustomer); 
      newId = newCustomer.Id; 
      tx.Commit(); 
     } 

     using (var session = sessionFactory.OpenSession()) 
     using (var tx = session.BeginTransaction()) 
     { 
      var newCustomer = session.Load<Customer>(newId); 
      Console.WriteLine("\nAfter saving:"); 
      Console.WriteLine(newCustomer); 
      session.Save(newCustomer); 
      tx.Commit(); 
     } 

     Console.WriteLine("Enter any key to exit..."); 
     Console.ReadKey(); 
    } 

    private static Customer CreateCustomer() 
    { 
     return new Customer 
     { 
      FirstName = "Jonh", 
      LastName = "Doe", 
      Points = 100, 
      HasGoldStatus = true, 
      //    MemberSince = new DateTime(2012, 1, 1), 
      CreditRating = CustomerCreditRating.Neutral, 
      AverageRating = 42.44454647, 
      Adress = new Location() 
      { 
       Street = "123 Somewhere Avenue", 
       City = "Nowhere", 
       Province = "Alberta", 
       Country = "Canada" 
      } 
     }; 
    } 
} 
} 

但是当我试图调试我的申请，我得到了HibernateConfigException 的“装配”属性未声明

如何解决t帽子？

UPD如果我删除从hibernate.cfg.xml文件属性assembly和namespace我得到其他错误
MappingException了未处理

UPD2我的映射文件（生成操作=嵌入式Resource）

<?xml version="1.0" encoding="utf-8" ?> 
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" 
        assembly="NHibernateDemo" 
        namespace="NHibernateDemo"> 
    <class name="Customer"> 
     <id name="Id"> 
      <generator class="native" /> 
     </id> 
    <property name="FirstName"/> 
    <property name="LastName"/> 
    <property name="AverageRating"/> 
    <property name="Points"/> 
    <property name="HasGoldStatus"/> 
    <property name="MemberSince" type="UtcDateTime"/> 
    <property name="CreditRating" type="CustomerCreditRatingType"/> 

    <component name="Adress"> 
     <property name="Street"/> 
     <property name="City"/> 
     <property name="Province"/> 
     <property name="Country"/> 
    </component> 
</class> 
</hibernate-mapping>

您需要添加assambly代码：

var cfg = new Configuration(); 
    cfg.AddAssembly("NHibernateDemo"); 
    cfg.Configure("hibernate.cfg.xml");
