How would this Scala code look in idiomatic C#?

Question

I came across this really nice looking Scala code while researching XMPP for a .Net project we're working on:

object Main {

  /**
   * @param args the command line arguments
   */
  def main(args: Array[String]) :Unit = {
      new XMPPComponent(
        new ComponentConfig() {
            def secret() : String = { "secret.goes.here" }
            def server() : String = { "communitivity.com" }
            def subdomain() : String = { "weather" }
            def name() : String = { "US Weather" }
            def description() : String = { "Weather component that also supported SPARQL/XMPP" }
        },
       actor {
        loop {
            react {
                case (pkt:Packet, out : Actor) =>
                    Console.println("Received packet...\n"+pkt.toXML)
                    pkt match {
                        case message:Message =>
                            val reply  = new Message()
                            reply.setTo(message.getFrom())
                            reply.setFrom(message.getTo())
                            reply.setType(message.getType())
                            reply.setThread(message.getThread())
                            reply.setBody("Received '"+message.getBody()+"', tyvm")
                            out ! reply
                        case _ =>
                            Console.println("Received something other than Message")
                    }
                 case _ =>
                    Console.println("Received something other than (Packet, actor)")
            }
        }
       }
    ).start
  }
}

The actor and pattern matching stuff looks like a really nice way to write components in a scalable way. I haven't been able to find any C# actors libraries that look mature, and learning Axum seems like overkill.

What would be the right way to attack this in C#? (ignoring the XMPP specific code, of course - I'm more interested in what the C# version of actors and pattern matching would look like).

Answer 1

There are Actor like libraries avaliable for .NET see retlang for one, also F# agents are similar.
