title: Is Microsoft.ServiceFabric.Actors.Runtime.ActorService thread-safe?
body: <p>About the Microsoft.ServiceFabric.Actors.Runtime.Actor, I know it single-threaded execution from the document <a href="https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-reliable-actors-introduction" rel="nofollow noreferrer">"An actor is an isolated, independent unit of compute and state with single-threaded execution. "</a>.</p>
  
  <p>Is Microsoft.ServiceFabric.Actors.Runtime.ActorService thread-safe? There are few document about it. We used it in our application, It seems not thread-safe in multi-nodes and multi-instance. Does anyone know about this?</p>
