AK1008 - Warning

Creating actors using Context.System.ActorOf() inside an actor is discouraged because the resulting actor would not be the child of this actor but the "/user" guardian actor itself. Please use Context.ActorOf() if your intention is to create a child actor of this actor.

Cause

Creating an IActorRef Using Context.System.ActorOf() or Context.System.ActorOf<T>() inside a class that inherits ReceiveActor or UntypedActor would create an actor as a child the "/user" guardian actor instead of a child actor under the invoking actor.

You can suppress this warning message if you specifically intended to create a new actor under the "/user" guardian actor.

Example:

using System;
using Akka.Actor;

public sealed class FirstActor : ReceiveActor
{
    public FirstActor()
    {
        Context.System.ActorOf<MyActor>("newActor");
    }
}

public sealed class MyActor : ReceiveActor
{
}

Resolution

Use Context.ActorOf() or Context.ActorOf<T>() method instead to create a new child actor:

using System;
using Akka.Actor;

public sealed class FirstActor : ReceiveActor
{
    public FirstActor()
    {
        Context.ActorOf<MyActor>("newActor");
    }
}

public sealed class MyActor : ReceiveActor
{
}
