Lifecycle and scheduling

Timers​

system.ScheduleOnce(counter, new Increment(), TimeSpan.FromSeconds(1));

system.StartPeriodicTimer(
    counter, "counter-timer", new Increment(),
    initialDelay: TimeSpan.Zero,
    interval: TimeSpan.FromSeconds(1));

system.StopPeriodicTimer(counter, "counter-timer");
system.StopAllTimers(counter);

Struct variants use ScheduleOnceStruct and StartPeriodicTimerStruct.

Shutdown​

bool stopped = system.Shutdown(counter);
bool stoppedByName = system.Shutdown<CounterActor, Increment>("counter");

bool graceful = await system.GracefulShutdown(
    counter, TimeSpan.FromSeconds(5));

Schedule shutdown with ScheduleShutdown, and use ShutdownStruct or GracefulShutdownStruct for struct actors. Subscribe to context.OnPostShutdown for cleanup. await system.Wait() waits until known repositories have no pending messages and no actor is processing.
