QuartzNet VS TopShelf

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.

Ultimately still might be worth looking into creating our own templates for common console app style applications. For example, with TopShelf I don't bother creating Windows Service template applications any longer. I just create a console app, include TopShelf, Unity, NLog... and instant no-fuss-no-muss self-installing, dependency injected, easily logged Windows Service.

I like using NuGet: TopShelf to control the service because it's a little more friendly than Visual Studio's default service manager, but even the default one works fine.

We've always used Topshelf: http://topshelf-project.com/
