Hi,

I am new to NHibernate and getting error: "Could not compile the mapping document: Nhibernate.User.hbm.xml". I am sure I have set the Embedded Resource Property to true of xml file.

The mapping file:
<?xml version="1.0" encoding="utf-8" ?>
- <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2">
- <class name="NhibernateSample1.User,NhibernateSample1" table="Users" lazy="false">
- <id name="Id" column="Id" unsaved-value="0">
<generator class="identity" />
</id>
<property name="Name" />
<property name="Pwd" />
</class>
</hibernate-mapping>

The Config:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory name="NHibernate.Test">
<!-- properties -->
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
<property name="connection.connection_string">Data Source=VMWIN2003SEBASE;Initial Catalog=NHibernateSimpleDemo;Integrated Security=True;Pooling=False</property>
<property name="show_sql">true</property>
<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
<property name="use_outer_join">true</property>
<!-- mapping files -->
<mapping assembly="NhibernateSample1" />
</session-factory>
</hibernate-configuration>

The persistent class:
using System;
using System.Collections.Generic;
using System.Text;
namespace NhibernateSample1
{
public class User
{
private int _id;
private string _name;
private string _pwd;

public virtual int Id
{
get { return _id; }
set {_id = value; }
}

public virtual string Name
{
get { return _name; }
set { _name = value;}
}

public virtual string Pwd
{
get { return _pwd;}
set {_pwd = value;}
}
}
}

The NH code:
using System;
using System.Collections.Generic;
using System.Text;
using NHibernate;
using NHibernate.Cfg;
using NHibernate.Tool.hbm2ddl;
namespace NhibernateSample1
{
public class UserFixture_TL
{
private ISession session;
private ISessionFactory _sessions;
private ITransaction transaction;
public void Configure()
{
_sessions = new Configuration().AddClass(typeof(User)).BuildSessionFactory();
}

public UserFixture_TL()
{

}

public string AddName()
{
try
{
User u = new User();
u.Name = Guid.NewGuid().ToString();
u.Pwd = "124";
//This is the line getting the error
_sessions = new Configuration().AddClass(typeof(User)).BuildSessionFactory();

session = _sessions.OpenSession();
transaction = session.BeginTransaction();
{
session.Save(u);
transaction.Commit();
}
return u.Name;
}
catch (Exception ex)
{
throw ex;
}
finally
{
session.Close();
}
}

}
}


Thnaks in advance!

Is there an inner exception with more information ?

+-InnerException {"Could not instantiate dialect class NHibernate.Dialect.MsSql2005Dialect"}+ InnerException {"Exception has been thrown by the target of an invocation."}
+ InnerException {"The type initializer for 'NHibernate.NHibernateUtil' threw an exception."}
+ InnerException {"Could not load type 'System.DateTimeOffset' from assembly 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.":"System.DateTimeOffset"}

Never mind, I solved it. Thanks anyway.
