Nice and please add another step to dump composer autoload by typing:
composer dump-auto

Nice, thank you.

GREAT!! Tanks, it works fine :)

It's not working.

Also when using App::bind

App::bind('myapp', function() { return new \App\MyApp\MyApp; });

It gives an error

Method 'bind' not found in \Illuminate\Support\Facades\App
