Answer
- IOptions: Singleton configuration, loaded once.
- IOptionsSnapshot: Per-request config, refreshed each request.
- IOptionsMonitor: Live config with change notifications.
Quick Answer
Three options interfaces for different scenarios: IOptions never changes after startup (singleton). IOptionsSnapshot re-reads per request — good for config files with reloadOnChange: true. IOptionsMonitor notifies subscribers immediately when config changes — best for singletons that need live updates without restart.
