Answer
Lifetime events:
- ApplicationStarted
- ApplicationStopping
- ApplicationStopped
They allow warm-ups, cache initialization, graceful shutdowns, and log flushing.
Quick Answer
IHostApplicationLifetime provides hooks: ApplicationStarted fires when the host is ready (warm caches, connect to message brokers). ApplicationStopping fires when shutdown is requested but before it completes (drain connections, stop background work). ApplicationStopped fires when everything is done. Inject it into any service that needs lifecycle awareness.
