[Help wanted] Prevent the console app to got terminated after the Run method call

[nilobaz]

So, I'm testing the very friendly and initial examples like that:

var app = ConsoleApp.Create(args);
app.AddCommands<Foo>();
app.Run();

But when I build/run the app, my console just got terminated and I didn't have a chance to make any input. I tried to use Console.ReadLine() right after the app.Run() but it is not working and I didn't get the command response either.

The only way I was able to see it working was by calling this in the terminal at solution directory e.g. dotnet run -- sum 2 2

I would like to have something I could debug, is there a proper way or any tips to achieve that, please? I mean, something to keep console app open and just terminated with some command like e.g. --exit.

If an argument is wrong, invalid, etc., do you get any kind of message? Also, if Logging Level is set to Trace, more internal information is output.

Thanks for the update! I added ZLoger to it, and now we're getting more info.

When I use dotnet run -- sum z x it works as expected and we get the right information.

dotnet run -- sum z x
Hosting starting
ConsoleAppEngine.Run Start
Parameter "x" fail on JSON deserialize, please check type or JSON escape or add double-quotation. args: sum z x
Hosting started
Hosting stopping
Hosting stopped

But unfortunately, when I try to debug, it seems that the hosting got stopped right after the app.Run(). I tried to use Console.ReadLine() to send commands but without success, I got no output response. I guess it is because the hosting has stopped. I'm not sure if there's a way to prevent that and just let it stop when calling an exit command for example.

Hosting starting
ConsoleAppEngine.Run Start
Usage: test <Command>

Commands:
  echo      
  help       Display help.
  sum        
  version    Display version.

ConsoleAppEngine.Run Complete Successfully
Hosting started
Hosting stopping
Hosting stopped
test sum 2 3                 // no output msg
test sum z x                // no output msg
foo sum 2 3                // no output msg
foo sum z x               // no output msg

I'm not sure what you want to do or what the problem is, maybe you want to give parameters in Console.ReadLine?

If so, create new args...

var line = Console.ReadLine();
var newArg = line!.Split(' ');

var app = ConsoleApp.Create(newArg);
app.AddCommands<Foo>();
app.Run();

Yeah, that helps. I was calling Console.ReadLine after the app.Run(). I think I misunderstood how it works and I was expecting the console app to not get terminated after app.Run(). My apologies, and thanks for the help!
