Understanding Quartz.NET Jobs: IJob vs IJobDetail Explained

When you first start working with Quartz.NET, the most common question you’ll see on forums, in code reviews, or during architecture discussions is: “What’s the difference between IJob and IJobDetail?”
While they sound similar and both belong to the core scheduling engine, they serve distinctly different roles. Knowing when to use each—and how they interact—can save you from subtle bugs, improve maintainability, and unlock advanced features like dependency injection and concurrent‑execution control.
