Asp.net 在 IIS 10 上发布时出现核心错误

Question

我发布了我的应用程序并遇到了这个错误：

启动应用程序时出错。

.NET Core X64 v4.1.1.0 | Microsoft.AspNetCore.Hosting 版本 1.1.1 |微软 Windows 10.0.14393 |需要帮助吗？

查看日志文件：

Application started. Press Ctrl+C to shut down.

连接字符串：

{
  "Logging": {
    "IncludeScopes": false,
    "LogLevel": {
      "Default": "Warning"
    }
  },
  "ConnectionStrings": {
    "EstudantesCV21Context": "Server=myserver\SQLEXPRESS;Database=mydatabase;userid=myid;password=mypass"
  }
}

不知道你是否还需要这个问题的答案。我遇到了这个问题，我通过像这样更改连接字符串来解决它。添加双反斜杠

{ "Logging": { "IncludeScopes": false, "LogLevel": { "Default": "Warning" } }, "ConnectionStrings": { "EstudantesCV21Context": "Server=myserver\SQLEXPRESS;Database=mydatabase;userid=myid;password=mypass" } }
