NHibernate在单声道下抛出TypeLoadException

我有一个基于.Net的命令行应用程序与PostgreSQL 9.1交互（CRUD）。使用Nuget，该项目目前引用NHibernate 3.2.0.4000和FluentHibenrate 1.3.0.717NHibernate在单声道下抛出TypeLoadException

现在代码在.Net环境（意思是Windows Xp/7）下运行良好，但是在Mono下（Mono JIT编译器版本2.10.8.1（Debian 2.10.8.1-1ubuntu2.2）），我看到在NHibernate中的TypeLoadException从完全相同的代码（我没有重新编译任何单声道。）。有人可以帮忙指点吗？谢谢！

这里是堆栈跟踪

FluentNHibernate.Cfg.FluentConfigurationException: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.

下面是FluentNHibernateHelperPostgreSQL.CreateSessionFactory（）

private static ISessionFactory CreateSessionFactory() 
    { 
     FluentConfiguration fluentConfiguration = Fluently.Configure(); 
     PostgreSQLConfiguration standard = PostgreSQLConfiguration.Standard; 
     FluentConfiguration fluentConfiguration1 = fluentConfiguration.Database(((PersistenceConfiguration<PostgreSQLConfiguration, PostgreSQLConnectionStringBuilder>)standard).ConnectionString((PostgreSQLConnectionStringBuilder c) => c.FromConnectionStringWithKey("ConnectionStringKey"))); 
     ISessionFactory sessionFactory = fluentConfiguration1.Mappings((MappingConfiguration m) => m.AutoMappings.Add(FluentNHibernateHelperPostgreSQL.CreateAutomappings)).ExposeConfiguration(FluentNHibernateHelperPostgreSQL.BuildSchema).BuildSessionFactory(); 
     return sessionFactory; 
    }

它看起来像你的一个映射文档引用了Mono无法找到的类型。如果你在nHibernate中有log4net配置，你应该能够看到关于什么文档和它试图加载的类型的更多细节。为此，请将log4net appenders添加到您的配置文件中，如http://nhforge.org/wikis/howtonh/configure-log4net-for-use-with-nhibernate.aspx中所述，然后记得调用log4net.Config.XmlConfigurator（）在尝试创建sessionfactory前 – jakobandersen

我能够让log4net生成日志。但是，它尚未确定确切原因。无论哪种情况，log4net都显示代码能够生成 xml blob。唯一的区别是Windows输出'2012-09-18 01：18：27,508 [1] INFO NHibernate.Dialect.Dialect - 使用方言：NHibernate.Dialect.PostgreSQLDialect'而单声道输出'2012-09-18 01:03 ：31,529 [1] ERROR NHibernate.Cfg.Configuration - 无法编译映射文档：（XmlDocument）' 我需要再次使用log4net来查看它是否可以生成更深入的日志 – Antony

我会测试与单声道2.11.4 – knocte

的解决方案是手动部署最新单声道包从go-mono.com相关的代码正如评论部分中的knocte所示，2.11.4解决了这个问题。

我还没有尝试3.x，但到目前为止，我一直很高兴2.11.x没有理由跳入3.x船。
