Question

我创建了一个ASP.net MVC 5应用程序，不幸的是我的主机正在使用中等信任。当我使用＆＃34;〜/＆＃34;更改应用程序时，其他一切都有效。使用＆＃34; /＆＃34;在url路径中。现在我的麻烦是，当我使用以下代码创建表单时，应用程序在函数System.Web.Mvc.UrlHelper.GenerateUrl（）中抛出异常：

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

错误消息是：

应用程序尝试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，请与您的系统管理员联系或更改配置文件中的应用程序的信任级别。

以下是完整的堆栈跟踪：

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

Microsoft向托管商提供了指导，他们应该从Medium Trust迁移并使用适当的操作系统级隔离，因为中等信任现在被认为已过时。 http://support.microsoft.com/kb/2698981
