“插入用户时,解析查询时出错”

我开始学习NHibernate。我安装了最新版本并尝试运行一个非常简单的应用程序。有一个班级User

public class User
{
    public virtual Guid Id { get; set; }
    public virtual String Name { get; set; }
    public virtual int Age { get; set; }

    public override string ToString()
    {
        return string.Format("User{name='{0}', age={1}}", Name, Age);
    }
}

它的映射是:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
                   assembly="cs_nhibernate_test1"
                   namespace="cs_nhibernate_test1">

  <class name="User">
    <id name="Id">
      <generator class="guid" />
    </id>
    <property name="Name" />
    <property name="Age" />
  </class>
</hibernate-mapping>

然后,我的测试程序是这样的:

class Program
{
    static void Main(string[] args)
    {
        var cfg = new Configuration();
        cfg.Configure();
        cfg.AddAssembly(typeof (User).Assembly);
        new SchemaExport(cfg).Execute(false, true, true);

        ISessionFactory sessionFactory = cfg.BuildSessionFactory();
        using (ISession session = sessionFactory.OpenSession())
        {
            using (ITransaction transaction = session.BeginTransaction())
            {
                User user = new User { Name = "John Smith", Age = 25 };
                session.Save(user);
                transaction.Commit();
            }
        }
    }
}

hibernate.cfg.xml是这样的:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
    <property name="dialect">NHibernate.Dialect.MsSqlCeDialect</property>
    <property name="connection.driver_class">NHibernate.Driver.SqlServerCeDriver</property>
    <property name="connection.connection_string">Data Source=FirstSample.sdf</property>
    <property name="show_sql">true</property>
  </session-factory>

该项目是.NET 4.0项目,所有必需的文件似乎都在输出文件夹中。

我得到的错误是:

  

NHibernate:INSERT INTO用户(姓名,年龄,身份)VALUES(@ p0,@ p1,   @ p2); @ p0 ='John Smith'[类型:字符串(0)],@ p1 = 25 [类型:Int32   (0)],@ p2 = 4b0d4bbf-7d3c-4bff-908d-ecddfdd8a5cd [类型:指南(0)]

     

未处理的异常:System.Data.SqlServerCe.SqlCeException:在那里   解析查询时出错。 [令牌行号= 1,令牌行   offset = 13,Toke n in error = User]

关于修复它的任何想法?
