azure - .NET 5.0 Webjob 不再从独立构建开始

Question

由于 .NET 5.0，我将我的构建切换为独立的。我知道有一个预览运行时，但我不想在我的生产环境中押注于此。我遇到过预览运行时无意中切换回来的情况(例如横向扩展)。

dotnet publish --configuration release --self-contained true --runtime win-x64

完成独立构建后，我的网络作业不再启动。在查看日志时，我发现了这一点:

这个createdump日志输出是什么意思？

Answer 1

进行独立构建时，您的构建输出文件夹将包含一个 createdump.exe 文件。将 WebJob 部署到应用服务时，它现在将选择此 .exe 而不是您的 WebJob。这就是日志显示 createdump.exe 的 CLI 输出的原因。

解决方法:创建一个仅包含 mywebjob.exe 名称的 run.cmd 文件。

• Per file type we look first for a file named: run.{file type extension} (for example run.cmd or run.exe).
• If it doesn't exists for all file types, we'll then look for the first file with a supported file type extension.
• The order of file types extension used is: .cmd, .bat, .exe, .ps1, .sh, .php, .py, .js.
• The recommended script file to have in your job directory is: run.cmd.
• Note: We'll only look for a script under the root directory of that job (not under sub directories of it).
• Note: make sure .bat/.cmd files don't include the UTF-8 BOM (inserted by some editors such as Visual Studio by default), which can break things!

PS:您不能简单地删除createdump.exe，因为您的应用程序将not start without it 。编辑:如果您使用 net6 或更高版本，您现在可以删除该文件。
