Azure - How to build a WebJob using a Pipeline coded in a Yaml file

I am totally new to Azure, Pipelines, etc.

I am trying to create an App Service consisting of a web site and a WebJob (a background job that runs periodically). I want to build and deploy it using a Pipeline coded with a Yaml file.

I created a Visual Studio solution with a very simple ASP.Net Core web site (project "pipelines-dotnet-core"), and a simple .Net Core console program (project "WebJobsSDKSample").

I created the Yaml file to build, publish and deploy the web site to my App Service. This works fine and I can open the site in a browser.

I then extended the Yaml file to copy the output folder of the console program project to the publish folder of the web site, compress the result to a zip file and deploy that zip file. I understand that I have to copy the console program project output folder to /App_Data/jobs/triggered/app under the publish folder of the web site.

This new pipeline runs fine, and the web site still gets deployed correctly. However, when I open the WebJobs page of my App Service, it says "You haven't added any WebJobs".

The contents of my Yaml file is below. What do I need to change to correctly deploy the WebJob?

Also, if you could point me at clear examples of how to code a WebJob in a Yaml Pipeline file, that would be really helpful.
