升级到2.1.2版后,Nhibernate不起作用

我最近将我的NHibernate实现从版本2.1.0更改为2.1.2。对于延迟加载,我使用了LinFu实现:NHibernate.ByteCode.Linfu。

由于我更改为最新版本,因此出现以下错误:

 [SecurityException: That assembly does not allow partially trusted callers.]
  NHibernate.ByteCode.LinFu.ProxyFactory..cctor() +0

调试时出现以下错误:

   at NHibernate.ByteCode.LinFu.ProxyFactory..ctor()
   at NHibernate.ByteCode.LinFu.ProxyFactoryFactory.BuildProxyFactory()
   at NHibernate.Tuple.Entity.PocoEntityTuplizer.BuildProxyFactoryInternal(PersistentClass class, IGetter getter, ISetter setter)
   at NHibernate.Tuple.Entity.PocoEntityTuplizer.BuildProxyFactory(PersistentClass persistentClass, IGetter idGetter, ISetter idSetter)
   at NHibernate.Tuple.Entity.AbstractEntityTuplizer..ctor(EntityMetamodel entityMetamodel, PersistentClass mappingInfo)
   at NHibernate.Tuple.Entity.PocoEntityTuplizer..ctor(EntityMetamodel entityMetamodel, PersistentClass mappedEntity)
   at NHibernate.Tuple.Entity.EntityEntityModeToTuplizerMapping..ctor(PersistentClass mappedEntity, EntityMetamodel em)
   at NHibernate.Tuple.Entity.EntityMetamodel..ctor(PersistentClass persistentClass, ISessionFactoryImplementor sessionFactory)
   at NHibernate.Persister.Entity.AbstractEntityPersister..ctor(PersistentClass persistentClass, ICacheConcurrencyStrategy cache, ISessionFactoryImplementor factory)
   at NHibernate.Persister.Entity.SingleTableEntityPersister..ctor(PersistentClass persistentClass, ICacheConcurrencyStrategy cache, ISessionFactoryImplementor factory, IMapping mapping)
   at NHibernate.Persister.PersisterFactory.CreateClassPersister(PersistentClass model, ICacheConcurrencyStrategy cache, ISessionFactoryImplementor factory, IMapping cfg)
   at NHibernate.Impl.SessionFactoryImpl..ctor(Configuration cfg, IMapping mapping, Settings settings, EventListeners listeners)
   at NHibernate.Cfg.Configuration.BuildSessionFactory()
   at MyApplication.SessionManager..ctor() in C:\Projects\MyApps\MyApplication\SessionManager.cs:line 75

这是因为使用了NHibernate.ByteCode.LinFu吗?我该怎么做才能使应用程序再次运行?

如果您有不同版本的引用,即2.1.0和2.1.2,您可以使用程序集重定向将.net配置为将调用从旧调用重定向到新调用,反之亦然......

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
            <dependentAssembly>
                <assemblyIdentity name="Linfu.DynamicProxy"
                                  publicKeyToken="32cd8f1a53a4c744"
                                  culture="neutral" />
                <bindingRedirect oldVersion="1.0.0.0"
                                 newVersion="1.1.0.0"/>
            </dependentAssembly>
        </assemblyBinding>
    </runtime>
</configuration>

但是我不认为这是问题,因为错误是完全不同的。即安全例外。 “该程序集不允许部分信任的调用者”似乎表明正在运行的任何进程没有必要的上下文权限来执行方法“NHibernate.ByteCode.LinFu.ProxyFactory..ctor()”中的代码。您可能正在使用客户端配置文件或“部分受信任”的Web托管环境运行应用程序。

您是否有关于运行此应用程序的上下文的更多信息?
