AKKA.NET actor system not shut down correctly in asp.net core application -

i'm running akka.net actor system inside asp.net core application (framework net46). run web-application command prompt running 'dotnet run' , when try exit using ctrl-c following output , prompt hangs there:

                c:\d3\>19:05:33.7024266 env=d0 sdm.web debug akka.actor.internal.actorsystemimpl  disposing system             19:05:33.7084292 env=d0 sdm.web debug akka.actor.internal.actorsystemimpl  system shutdown initiated             [debug][12/09/16 19:05:33][thread 0023][eventstream] subscribing [akka://all-systems/] channel akka.event.debug             19:05:33.7134423 env=d0 sdm.web debug akka.actor.guardianactor  stopping             [debug][12/09/16 19:05:33][thread 0023][eventstream] subscribing [akka://all-systems/] channel akka.event.info             [debug][12/09/16 19:05:33][thread 0023][eventstream] subscribing [akka://all-systems/] channel akka.event.warning             [debug][12/09/16 19:05:33][thread 0023][eventstream] subscribing [akka://all-systems/] channel akka.event.error 

if hit ctrl-c exits. doesn't seem right.

i'm using dependency injection container manage life time of actor system (singleton-scope) assume container trying dispose object @ application shutdown.

can suggest might wrong?

you need directly stopping akka.net actors if want graceful shutdown. use application shutdown events provided asp.net core via iapplicationlifetime interface:

cancellationtoken applicationstopping { get; } cancellationtoken applicationstopped { get; } 

obtaining instance of iapplicationlifetime can done during startup.cs in configure method:

protected void disposeresources() {     //cleanup stuff when app shutting down }  public void configure(iapplicationbuilder app, iapplicationlifetime applicationlifetime) {     //register application shutdown handler     applicationlifetime.applicationstopping.register(disposeresources); }
