Asp.net core IIS 10上的.NET MVC Core 2部署问题

我正在尝试将我的ASP.NET MVC Core 2部署到运行IIS 10的Windows Server 2016服务器上，应用程序日志中出现以下错误

我研究了这个问题，发现这个问题的答案是：“由于VS2017 RC附带了新版本的.NET Core SDK（.NET Core 1.0.4 SDK 1.0.1），您还需要在服务器上更新framework。”

我已尝试按照上面的回答在服务器上安装SDK和运行时，但当我导航到该站点时仍然收到错误。

我如何解决这个问题

运行以下命令显示了真正的错误：

C:\Windows\system32>"C:\Program Files\dotnet\dotnet" C:\inetpub\wwwroot\{YOUR_IIS_SITE_NAME}\{YOUR_PROJECT_NAME}.dll

命令提示符中的结果如下，它告诉我连接字符串中有错误：

这看起来很有用，但它假设代码中有一个bug@Grantly我没有收到任何stackoverflow错误。但是您收到了以下异常代码：0xc00000fd（您尝试过重新安装吗？可能您尝试过，只是想问一下）嗨，Grantly。我终于发现了这个问题，并在下面发布了我的答案。非常感谢您的帮助：）
