【问题描述】：

我有一个 .NET Core 命令行应用程序，我已将其作为 Web 作业部署到 Azure。
当我尝试访问应用程序中的数据库时，我收到以下错误消息：

不确定是否有其他人遇到过同样的问题并找到解决方法或修复它。在过去的两天里，我一直在尝试解决这个问题，但没有成功。
谢谢。

【问题讨论】：

你能清理一下你的格式吗？
请参阅this page 了解最初的隔离步骤。

【解决方案1】：

好的，我发现了问题。有2个问题。

1.您需要确保Project.json中有以下内容：

"Microsoft.NETCore.App": {
        "version": "1.0.0",
        "type": "platform"
    },

我的没有 "type": "platform" 部分。

主要是你需要在项目的根目录下有一个名为 run.cmd 的文件，并将它包含在你的发布输出中：

@echo 关闭 dotnet NameOfYourProject.dll 进程

这些更改后一切正常。希望这将有助于其他人并节省他们的时间。

【解决方案2】：

和我一样，我变了。

"frameworks": {
    "netcoreapp1.0": {
      "imports": [
        "dotnet5.6",
        "portable-net45+win8"
      ]
    }
  }

到。

"frameworks": {
    "netcoreapp1.1": {
      "imports": [
        "dotnet5.6",
        "dnxcore50",
        "portable-net45+win8"
      ],
      "dependencies": {
        "Microsoft.NETCore.App": {
          "version": "1.1.0",
          "type": "platform"
        }
      }
    }
  },
