Answer 1

Add the use statement atop your controller class and then modify your controller to extend it:

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class YourController extends Controller
{
  // ...
}

That's it! You now have access to methods like $this->get() or $this->render() and many others.
