Iis ServerManager构造函数在测试环境中崩溃

我正在用MVC4构建一个控件应用程序，遇到了一个非常恼人的问题。当我在本地调试项目时，它运行良好。但是，当我将项目部署到测试服务器（Windows server 2008 R2）时，以下行中断：

ServerManager manager = new ServerManager("%windir%\\system32\\inetsrv\\config\\applicationhost.config");

非常感谢您的帮助

结果是引用了错误的Microsoft.Web.Administration版本。正确的版本是7.0.0.0。7.9.0.0在某种程度上是针对IIS Express的，这解释了为什么它在我的开发环境中工作。

我遇到了这个问题，尽管Visual Studio中DLL的属性声明为“7.0.0.0”，但我在记事本中打开了csproj文件，看到它是7.9.0.0。谢谢你的回答，这本可以帮我省下几个小时，只要试着找出哪里出了问题！
