MVC 3项目中的异常

一个MVC3.0RC项目出现了一个奇怪的错误。

看来我的申请没有成为 同质AppDomain 昨天天气很好,不知道发生了什么变化。

System.InvalidOperationException was unhandled by user code
Message=Dynamic operations can only be performed in homogenous AppDomain.
Source=System.Core

在Index.cshtml中修改View.Title时引发异常

@{
   View.Title = "Jobs | realjobs.com.au";
}

有什么想法吗?谷歌没有带来任何乐趣。

更新

似乎真的不喜欢我改变web.config中的信任

为了解决另一个问题,我添加了以下行:

<trust legacyCasModel="true" level="Full"/>

一旦被移除,它就会再次工作。这是故意的吗?
