just learning Akka - started Lesson 1: "ConsoleWriterActor() could not be found" error

[NetEyes]

I am using visual studio 2017. I'd install package Akka.
on the Program.cs Main .. as instructed on the lesson. I added

var consoleWriterActor = MyActorSystem.ActorOf(Props.Create(() =>
new ConsoleWriterActor()));
var consoleReaderActor = MyActorSystem.ActorOf(Props.Create(() =>
new ConsoleReaderActor(consoleWriterActor)));

"ConsoleWriterActor() could not be found" error. Please advise what library to be added other than Akka.Actor

It looks like you skipped over the Launch the fill-in-the-blank sample section

The ConsoleWriterActor is defined in the DoThis project
