我很难让 asp.net 4.0 以任何方式工作。事实上，我彻底清除了我的服务器，重新安装了 Server 2008 R2 Standard（在 VMWare ESXi 机器上运行，这并不重要），甚至无法让测试 .aspx 页面正常工作。
这正是我所做的：
- 安装 2008 R2 标准
- 激活的窗口和启用的远程桌面
- 安装了具有必要角色服务的 Web 服务器角色（常见的 http、asp.net、日志记录、跟踪、管理服务和 FTP）
- 启用管理服务
- 通过 Web 可执行文件安装 .Net Framework 4.0
- 将 FTP 发布添加到默认网站
- 将默认网站应用程序池切换到 asp.net 4.0（集成）
- 在 inetpub\wwwroot 文件夹中添加了一个“test.aspx”文件（内容如下）
- 打开浏览器访问http://localhost/test.aspx并收到 500.0 错误（也在下方）
我错过了什么？我有一段时间（3 年以上）没有接触过 IIS，所以这可能是一些愚蠢/琐碎的事情。请指出，叫我菜鸟；我的自我可以接受。
谢谢，戴夫
