asp.net-mvc – 自动捆绑/缩小是否已在最终版本的MVC 4中获得？

<link href="Styles/reset.css" rel="stylesheet" type="text/css" />
<link href="Styles/normalize.css" rel="stylesheet" type="text/css" />
<link href="Styles/styles.css" rel="stylesheet" type="text/css" />

<script src="Scripts/jquery-1.8.0.min.js" type="text/javascript"></script>
<script src="Scripts/jquery-validation.min.js" type="text/javascript"></script>

有了这个：

<link href="Styles/css" rel="stylesheet" type="text/css" />

<script src="Scripts/js" type="text/javascript"></script>

我尝试过针对.Net 4.0和4.5,但它似乎没有什么区别.我收到404错误,链接和脚本标记从不指向捆绑的资源.

这个功能是否从最终版本中删除了？

我想将此功能用于“主题”.

这就是我最终实现的方式.希望它有意义……
