Asp.net 5使用IHttpConnectionFeature后停止工作

Question

我试图在Asp.net Vnext中获取远程IP地址。

在我的代码中添加此行后，页面在已发布的IIS中停止工作

服务器（不显示错误，只有白屏）：

var remoteIpAddress = HttpContext.Features.Get<IHttpConnectionFeature>()?.RemoteIpAddress;

当我在本地IIS-Express中检查结果时，它给了我：

这是我的project.json文件：

{
  "version": "1.0.0-*",
  "compilationOptions": {
    "emitEntryPoint": true
  },

      }
    }
  },

  "exclude": [
    "wwwroot",
    "node_modules"
  ],
  "publishExclude": [
    "**.user",
    "**.vspscc"
  ]
}

此外我正在使用普通的IIS 8进行我的项目，我不会将此程序移植到另一个操作系统。

我应该更改项目json中的“Web”部分吗？喜欢添加iis还是什么？
