我发布了我的应用程序并收到此错误：

启动应用程序时出错。

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

查看日志文件：

连接字符串：

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

【问题讨论】：

你看过这个吗？ stackoverflow.com/questions/35663759/…
我不知道，但我认为不是，我在 Windows Server 16 上发布，更改连接字符串后出现此错误。
这不是解决方案，但请按照该答案查看实际错误是什么。 “启动应用程序时发生错误”非常通用，可以让任何人真正了解解决您的问题。
我提出了登录问题，我需要修复字符串连接。
您连接到什么数据库... SQLOLEDB 真的很旧，并且没有与 SQL Server 或 SQLite 一起用于 EFC... 您能否向我们展示您的连接字符串原因，这会有所启发关于这个问题。

【解决方案1】：

我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" } }
