Workflow Core VS QuartzNet

I haven't tried it out myself but this library might fit your needs: https://github.com/danielgerlag/workflow-core

This looks suspiciously like Workflow-Core, but they are separate projects.

To ease orchestration, something like Workflow Core might be useful in reducing boilerplate setup within batch processes.

I would agree with using Job over Queue. Therefore I would recommend looking at Quartz.Net https://www.quartz-scheduler.net/

You can use something like https://www.quartz-scheduler.net/ to create multiple recurring jobs based on the definition you load from a DB.

Or use an existing open source scheduling solution like https://www.quartz-scheduler.net/

If you're interested in using Quartz, you can check out their GitHub repo here: https://github.com/quartznet/quartznet. They also have extensive documentation available on their website: https://www.quartz-scheduler.net/documentation/index.html.

You should use an actual scheduler. https://www.quartz-scheduler.net/

Better to use a framework like Quartz.NET for scheduling background tasks. How it works inside the box I have no idea, but I have used it extensively in my web applications, and those background tasks run 24/7, come hell or high water. It's a good library, and it's easy to use.
