Can't execute .net 5 program as Azure WebJob

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.

Solution

  • Here are some operation might help.

    1. Explicitly configure your App Service to use the .NET 5 stack. enter image description here

    2. Install extensions for background webjob. enter image description here enter image description here

    3. You can also go to kudu for extensions installation. enter image description here
