Sooner or later, every ASP.NET Core application needs to do work outside the request pipeline: sending emails, generating reports, syncing data with a third-party API, or cleaning up stale records at 2 AM. That's when developers start searching for how to run background jobs in .NET — and immediately run into three popular options: Hangfire , IHostedService (with its BackgroundService base class), and Quartz.NET .
