Actor context

Ask for a typed context in the actor constructor. Nixie provides it automatically:

public sealed class ParentActor : IActor<string>
{
    private readonly IActorContext<ParentActor, string> context;
    private readonly IActorRef<ChildActor, string> child;

    public ParentActor(IActorContext<ParentActor, string> context)
    {
        this.context = context;
        child = context.ActorSystem.Spawn<ChildActor, string>();
    }

    public Task Receive(string message)
    {
        child.Send(message, context.Self);
        return Task.CompletedTask;
    }
}

Member	Purpose
ActorSystem	The system that owns the actor.
Self	A typed reference to the current actor.
Sender	The supplied sender reference, when present.
Logger	The logger configured on the actor system.
OnPostShutdown	Register cleanup work after shutdown.

Request/response contexts also expose Reply and ByPassReply for advanced reply flows.

:::note Execution context isolation Actor handlers run on the default ExecutionContext. Ambient sender values such as AsyncLocal do not flow into the handler. Put request-scoped data in the message explicitly. :::
