title: Quartz, Quartz.Jobs and Quartz.AspNetCore Nuget Packages
body: <p>I'm trying to understand the differences between Quartz, Quartz.Jobs, and the Quartz.AspNetCore NuGet packages.</p>
  <p>What does Quartz.Jobs provide that is not in the Quartz package, when should I use it and why?</p>
  <p>The same question applies to Quartz.AspNetCore. What does it provide and when should I use it?</p>
