波浪号斜线路径在MVC 4不工作

由于我理解，一个普通的醇'〜/ foo的路径应该像@ Url.Content工作（〜/）在MVC 4。但是，我想做到这一点，越来越多破碎的路径 - 中波浪仍然存在，当HTML输出。

As I understand it, a plain ol' "~/foo" path is supposed to work like @Url.Content("~/") in MVC 4. However, I'm trying to do this and getting many broken paths -- the tilde is still there when the HTML is output.

因此​​，举例来说，我在/Views/Shared/_Layout.cshtml这个路径：

So, for example, I have this path in /Views/Shared/_Layout.cshtml:

<link href="~/Content/Site.css" rel="stylesheet" type="text/css" />

和HTML交付看起来是这样的：

And the HTML delivered looks like this:

<link href="~/Content/Site.css" rel="stylesheet" type="text/css" />

我是pretty相信我有这个运行作为一个MVC 4项目了。下面的东西是在web.config：

I'm pretty sure I have this running as an MVC 4 project, too. The following stuff's in the web.config:

<compilation debug="true" targetFramework="4.0">
  <assemblies>
    <add assembly="System.Web.Abstractions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.Helpers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.Routing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
    <add assembly="System.Web.WebPages, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
  </assemblies>
</compilation>

...在这一点上，我不知道该怎么寻找下一个。有什么建议？

...and at this point, I'm not sure what to look for next. Any suggestions?
