Asp.net core 3.1 - InProcess on Azure 应用服务 HTTP 错误 500.31 - ANCM 无法找到本机依赖项

Question

我已将我的项目迁移到 asp.net core 3.1，但是当我部署到 azure web 应用程序时，它无法启动。

显示错误

HTTP 错误 500.31 - ANCM 未能找到常见的本机依赖项 此问题的解决方法：指定版本 未找到 Microsoft.NetCore.App 或 Microsoft.AspNetCore.App。 故障排除步骤：检查系统事件日志中的错误消息 启用记录应用程序进程的标准输出消息 调试器到应用程序进程并检查

我认为问题在于 dotnet info 返回 win10-x86 的位数，但是当我创建新的核心应用程序并从 Visual Studio 部署时，它运行良好。

Answer 1

太疯狂了。。我花了一个星期后，在我进行 web.config 转换并将其更改为 stdoutLogFile="\\?\%home%\LogFiles\stdout" 后，问题变成了 stdoutLogFile=".\logs\stdout" 现在它可以工作了

Answer 2

因此，Azure 中的 ANCM 错误似乎从未真正对应于 ANCM 消息。例如，如果它抱怨缺少依赖项，可能是因为 Startup.cs 中抛出了未处理的异常。是的。

查看“真实”错误的最快方法是尝试从 Kudu 运行应用程序（Azure 应用程序 -> 开发工具部分 -> 高级工具 -> “Go”，使用浏览器内终端运行 MyApp.exe只需输入其路径并按回车键）。解决 ANCM 错误后，您将看到“应用程序在 localhost:5000 上启动”或类似内容。否则，它会显示一个堆栈跟踪，告诉您确切的问题是什么。
