ASP.. NET MVC4不能在IIS中呈现布局

一直在使用ASP。. NET和MVC几年了，以前从未见过这个…

刚收到一台新机器。创建了一个新的MVC4 Web项目(在向导中用于Internet)。我使用项目的权利"开箱即用"来测试一切都是正确的设置和配置。

如果我使用内置的web服务器从Visual Studio(2010)运行它，那么一切都很好。然而，我在IIS中设置了一个应用程序，它没有渲染布局(默认生成的代码在默认位置~/Views/Shared/_Layout.cshtml)，但我确实得到了索引。cshtml (~/Views/Home/Index.cshtml)内容布局中没有任何内容被渲染:没有html标签，没有样式，没有javascript，没有body标签，什么都没有。

Did the basic diagnostics…IIS中没有显示服务器错误。在事件/应用程序日志中没有记录为错误的内容。在Chrome网络检查工具中没有显示任何内容(甚至404或500也没有)

任何想法?我难住了……有一种感觉，这是一件非常非常简单的事情。

索引。cshtml(默认生成的代码，除了我在底部的测试代码，只是为了确保MVC dll被正确拾取):
