System.Security.Permissions.ReflectionPermission错误nHibernate 3.3.1

Question

我正在尝试让我的ASP.NET 4.0编写的web应用程序在本地使用中等信任。我使用Go Daddy作为web主机，而他们在共享主机上使用中等信任。我读到过nHibernate现在可以在3.3版本中开箱即用地使用Medium Trust站点，但我永远不能让我的站点工作。

只需添加以下内容：

<trust level="Medium" />

对于我的web.config，我的web应用程序会出现以下错误和堆栈跟踪：

Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

这似乎是我读到的相同的错误，但到目前为止，我找到的修复方法似乎都不适用于我。我甚至尝试过NHibernate.DependencyInjection Nuget包，但错误输出时出现了相同的错误，但堆栈跟踪不同，这发生在初始化器ctor中。

我觉得我遗漏了一些明显的东西来完成这项工作，但我不能确定它。有没有人在中等信任下运行过nHibernate 3.3.1？

Answer 1

我可以通过关闭ado批处理来让它工作。我在这里找到了答案http://blog.ondrejsv.com/post/N2CMS-NHibernate-SqlCommandSet-and-medium-trust.aspx警告，我还没有将其迁移到生产环境中；这只是在我的笔记本电脑(YMMV)上。

<property name="adonet.batch_size">0</property>

我尝试过NHibernate.DependencyInjection包，但它不起作用。

希望这能有所帮助。

Answer 2

我与中等信任提供商一起使用开箱即用的NH3.3.1。然而，也许还有其他东西可以帮助你。由兰兹利安装此package：-

PM> Install-Package NHibernate.DependencyInjection

要启动并运行它，只需使用

protected void Application_Start() {
  Initializer.RegisterBytecodeProvider();
  ...
  Rest of configuration code here
