Load Akka Config from App.config automatically

[Aaronontheweb]

I would love to be able to remove the following boilerplate code from Akka.NET apps if possible:

var section = (AkkaConfigurationSection)ConfigurationManager.GetSection("akka");
var config = section.AkkaConfig;
var actorSystem = ActorSystem.Create("MySystem", config);

And just have the following call, which would automatically load configuration sections in via ConfigurationManager:

var actorSystem = ActorSystem.Create("MySystem");

Any objections to this?

I think this makes sense.

Also, very soon the internal behavior will probably need some change to work with the new config providers from asp.net vnext, that don't require xml files. In that case, akka can load the settings directly from some hocon file with some config.AddHoconFile('akka.config').

This is already how it works...

@rogeralsing here's what ConfigurationFactory.Load() currently does:

 var section = new AkkaConfigurationSection();
 Config config = section.AkkaConfig;

return config;

https://github.com/akkadotnet/akka.net/blob/dev/src/core/Akka/Configuration/ConfigurationFactory.cs#L38

This returns a blank Config, not the Config stored in App.Config or Web.config.

Needs to be changed to using the ConfigurationManager to load from App.config.

Ohhh. that is a bug in that case.

I'm having Bootcamp attendees use this in Unit 2 - would love to have a hotfix for this for them in the near future :p

This is broken in the latest release of Akka.Net 1.4.1. Please reopen this issue. It is no longer automatically loading the akka section in the app.config file. Reverting back to 1.3.18 works fine.

Open a new issue.
