我有一个 5命令行程序，我试图按计划在Azure上以webjob的身份执行该程序.我可以在本地执行它而不会出现问题，但是在Azure上执行时，我得到:

但是根据我在这里看到的内容:

为后台网络作业安装扩展程序.

您也可以转到kudu进行扩展程序安装.

I have a 5 command line programm which I try to execute on a schedule as webjob on Azure. I can execute it without issues locally, but when execute on Azure I get:

[12/14/2020 21:28:03 > 83e1e9: SYS INFO] Status changed to Initializing [12/14/2020 21:28:10 > 83e1e9: SYS INFO] Run script 'ApplySupportTool.ServerTasks.exe' with script host - 'WindowsScriptHost' [12/14/2020 21:28:11 > 83e1e9: SYS INFO] Status changed to Running [12/14/2020 21:28:11 > 83e1e9: ERR ] It was not possible to find any compatible framework version [12/14/2020 21:28:11 > 83e1e9: ERR ] The framework 'Microsoft.NETCore.App', version '5.0.0' was not found.

But from what I read here: azure.github.io/AppService/2020/11/10/Dot-Net-5-on-App-Service.html 5 is already available through all regions. Also, my 5 asp core web api project works without issues on the same app service. I also tried to install it explicitly via the ASP.NET Core 5.0 (x86) Runtime, but with no different result. I know that I can publish it as self contained. Given the size increase I would prefer to use the installed version though.

解决方案

Here are some operation might help.

Explicitly configure your App Service to use the .NET 5 stack.

Install extensions for background webjob.

You can also go to kudu for extensions installation.
