用VS2012新建了一个MVC4的项目后在本地用iis express调试没有问题，但是发布到一台win2008 r2上的IIS7.5之后，用IE一访问就会进入IE8兼容视图，IE7标准文档模式。
默认_layout.html如下：
<!DOCTYPE html>
<html lang="zh">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<meta charset="utf-8" />
<title>@ViewBag.Title - 我的 ASP.NET MVC 应用程序</title>
<link href="~/favicon.ico" rel="shortcut icon" type="image/x-icon" />
<meta name="viewport" content="width=device-width" />
@Styles.Render("~/Content/css")
@Scripts.Render("~/bundles/modernizr")
</head>
<body>
<header>
<div class="content-wrapper">
<div class="float-left">
<p class="site-title">@Html.ActionLink("将你的徽标放置在此处", "Index", "Home")</p>
</div>
<div class="float-right">
<section id="login">
@Html.Partial("_LoginPartial")
</section>
<nav>
<ul id="menu">
<li>@Html.ActionLink("主页", "Index", "Home")</li>
<li>@Html.ActionLink("关于", "About", "Home")</li>
<li>@Html.ActionLink("联系方式", "Contact", "Home")</li>
</ul>
</nav>
</div>
</div>
</header>
<div id="body">
@RenderSection("featured", required: false)
<section class="content-wrapper main-content clear-fix">
@RenderBody()
</section>
</div>
<footer>
<div class="content-wrapper">
<div class="float-left">
<p>© @DateTime.Now.Year - 我的 ASP.NET MVC 应用程序</p>
</div>
</div>
</footer>
@Scripts.Render("~/bundles/jquery")
@RenderSection("scripts", required: false)
</body>
</html>
生成的代码如下：
<!DOCTYPE html>
<html lang="zh">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<meta charset="utf-8" />
<title>Home Page - 我的 ASP.NET MVC 应用程序</title>
<link href="/favicon.ico" rel="shortcut icon" type="image/x-icon" />
<meta name="viewport" content="width=device-width" />
<link href="/Content/css?v=WMr-pvK-ldSbNXHT-cT0d9QF2pqi7sqz_4MtKl04wlw1" rel="stylesheet"/>
<script src="/bundles/modernizr?v=qVODBytEBVVePTNtSFXgRX0NCEjh9U_Oj8ePaSiRcGg1"></script>
</head>
<body>
<header>
<div class="content-wrapper">
<div class="float-left">
<p class="site-title"><a href="/">将你的徽标放置在此处</a></p>
</div>
<div class="float-right">
<section id="login">
<ul>
<li><a href="/Account/Register" id="registerLink">注册</a></li>
<li><a href="/Account/Login" id="loginLink">登录</a></li>
</ul>
</section>
<nav>
<ul id="menu">
<li><a href="/">主页</a></li>
<li><a href="/Home/About">关于</a></li>
<li><a href="/Home/Contact">联系方式</a></li>
</ul>
</nav>
</div>
</div>
</header>
<div id="body">
<section class="featured">
<div class="content-wrapper">

现在只能用<meta http-equiv="X-UA-Compatible" content="IE=edge" >虽然文档模式用了最新版本但是浏览器模式仍然是兼容模式……
解决方法： 因为这个问题在评论中，所以在题中更新一下解决方案。
Theo · 44分钟前 回复徐牛: IE的Compatibility view有个设置，默认是intranet开启compatibility view，你可以看看是不是这个问题：http://blogs.msdn.com/b/ie/archive/2009/06/17/compatibility-view-and-smart-defaults.aspx
检查IIS设置，HTTP头里面的
X-UA-Compatible是不是设置成了IE=8另外，顺带检查一下web.config,
customHeaders是不是有X-UA-Compatible这条。EDIT: 补充来自评论的答案
