无法将.net 5程序作为Azure WebJob执行 [英] Can't execute .net 5 program as Azure WebJob

问题描述

我有一个.net 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 .net 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:

But from what I read here: https://azure.github.io/AppService/2020/11/10/Dot-Net-5-on-App-Service.html .net 5 is already available through all regions. Also, my .net 5 asp.net 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.

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

2. Install extensions for background webjob.

3. You can also go to kudu for extensions installation.
