NHibernate在單聲道下拋出TypeLoadException

我有一個基於.Net的命令行應用程序與PostgreSQL 9.1交互（CRUD）。使用Nuget，該項目目前引用NHibernate 3.2.0.4000和FluentHibenrate 1.3.0.717NHibernate在單聲道下拋出TypeLoadException

現在代碼在.Net環境（意思是Windows Xp/7）下運行良好，但是在Mono下（Mono JIT編譯器版本2.10.8.1（Debian 2.10.8.1-1ubuntu2.2）），我看到在NHibernate中的TypeLoadException從完全相同的代碼（我沒有重新編譯任何單聲道。）。有人可以幫忙指點嗎？謝謝！

這裏是堆棧跟蹤

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; 
    }

它看起來像你的一個映射文檔引用了Mono無法找到的類型。如果你在nHibernate中有log4net配置，你應該能夠看到關於什麼文檔和它試圖加載的類型的更多細節。爲此，請將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，然後記得調用log4net.Config.XmlConfigurator（）在嘗試創建sessionfactory前 – jakobandersen

我能夠讓log4net生成日誌。但是，它尚未確定確切原因。無論哪種情況，log4net都顯示代碼能夠生成 xml blob。唯一的區別是Windows輸出'2012-09-18 01：18：27,508 [1] INFO NHibernate.Dialect.Dialect - 使用方言：NHibernate.Dialect.PostgreSQLDialect'而單聲道輸出'2012-09-18 01:03 ：31,529 [1] ERROR NHibernate.Cfg.Configuration - 無法編譯映射文檔：（XmlDocument）' 我需要再次使用log4net來查看它是否可以生成更深入的日誌 – Antony

我會測試與單聲道2.11.4 – knocte

的解決方案是手動部署最新單聲道包從go-mono.com相關的代碼正如評論部分中的knocte所示，2.11.4解決了這個問題。

我還沒有嘗試3.x，但到目前爲止，我一直很高興2.11.x沒有理由跳入3.x船。
