System.Web.Mvc.UrlHelper.GenerateUrl错误安全异常

Question

我创建了一个ASP.net MVC 5应用程序，不幸的是我的主机使用中等信任。当我改变应用程序使用“〜/”在URL路径中使用“/”时，其他所有工作都能正常工作。现在我的问题是，应用程序在功能System.Web.Mvc.UrlHelper.GenerateUrl抛出异常（）当我创建一个表格下面的代码：

@using (Html.BeginForm("Index", "Home", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" })) 

的错误信息是：

应用程序试图执行安全策略不允许的操作。要授予此应用程序所需的权限，请联系您的系统管理员或更改配置文件中的应用程序信任级别。

以下是完整的堆栈跟踪：

中等信任支持已从MVC，WebAPI，SignalR等中删除，现在需要完全信任。

微软已经向托管服务提供了指导，他们应该从中信任迁移并使用适当的操作系统级别的隔离，而现在认为中信托已经过时。 http://support.microsoft.com/kb/2698981
