I wonder how does it compare to Quartz.NET in terms of functionalities, reliability and scalability ? Has anyone used hangfire in production?

Quartz.NET is built around a scheduler, HangFire is built on top of message queues. If you want to off-load a task from the request processing pipeline, message queue is more preferable solution, because it can greatly reduce the latency of background job processing.
