如何在新的VS2013 Asp.net模板中禁用System.Security.Permissions.ReflectionPermission用法,以便它可以在共享主机上运行

Question

我从默认的MVC模板创建了一个全新的Visual Studio 2013 ASp.net MVC应用程序.但是我收到错误消息请求类型'System.Security.Permissions.ReflectionPermission的权限失败.

是否可以关闭此反射权限,以便网站仍然有效？

这是我的web.config

我试着补充一下

<trust level="Full" />

到我的Web.Config system.Web部分但是没有工作,因为我得到了

此配置部分不能在此路径中使用.当站点管理员使用继承的配置文件锁定对此节的访问权限时,会发生这种情况.

它是1and1.com的共享主机,他们不会给我完全的信任.

Answer 2

我直接询问了asp.net团队,这是他们的回应

我们正式宣布部分信任不再是去年申请隔离的信任边界(http://support.microsoft.com/kb/2698981),因此我们对共享托管服务提供商的建议是不再使用它.展望未来,我们不会支持部分信任我们为此开发的新框架功能.

我知道很多人使用共享主机,因为主机提供商不会完全信任他们的共享主机产品我猜测微软做出了这个决定,因此他们可以在Azure上获得更多客户.

让我们的小型开发人员在共享主机上出售困境.要么去更昂贵的托管或跳到天蓝色.
