What about naming the desired class witht he full qualifyed name?

Try to replace SliderRepository by \Site\Repositories\SliderRepository.

Controllers are in the root namespace () but your class is in another namespace, so your issue seems to be normal (or I am missing something here)

Thanks for your fast answer atrakeur

If I do that change, it works:

public function __construct(\Site\Repositories\SliderRepository $sliderRepository){

But I wanna to use Automatic resolution http://laravel.com/docs/ioc#automatic-resolution. Indeed, with this change i don't need even a ServiceProvider.

Thank you again.

Get rid of the lib directory and just use Site as a child folder of app

Then use psr-4 to autoload everything in your site folder:

"psr-4": {
    "Site\\": "app/Site"
 }

then

composer dump

Your class will be found. You don't need to make an IoC binding if you just want to inject a concrete repository into the constructor. However, service providers are a useful place to bind concrete classes to an interface if you are planning to inject interfaces into the controller and have them automatically resolved.

As Anthony mentions above, you should autoload using the namespace, that'll simplify things for you. Also, when binding you can simply do:

$this->app->bind('SliderRepository', 'Site\Repositories\SliderRepository');

This means that later down the line you can use injection on your repository, I for example inject a validator :)

Yes! Thanks Anthony and Ollie, I guess there is an issue in docs because there are a lot of ways to bind classes in IoC (on different versions of laravel). So, the fix was do it without the bind and inject directly with the concrete type. Now is working.

I owe you a couple of beers guys :D
