Quartz.NET 4.2.0 ships a Roslyn analyzer that rejects unparseable cron literals as QZ0001 at compile time, plus a source generator that turns [QuartzJob] and [CronTrigger] attributes into an AddDeclaredJobs() registration. Here is what it checks, what the generated code looks like, and how to opt out.

Use Quartz.NET when an LLM job must run on a real cron and never overlap itself, Hangfire when each run must survive a restart and retry on rate limits, and a plain BackgroundService only for a loose in-process loop. A decision matrix with the cron and concurrency gotchas that pick for you.
