Answer 1

You need to remove this outdated package (taken out of the core and no longer supported):

"illuminate/html": "^5.0",

When you remove it, you need to also remove its service providers / aliases. So, if you open up config/app.php, you will see a providers and aliases section. Remove these lines of code if you haven't done so already.

'Illuminate\Html\HtmlServiceProvider'

'Form'=> 'Illuminate\Html\FormFacade', 
'HTML'=> 'Illuminate\Html\HtmlFacade',

In place of it, you should install the Laravel collective package. To install that, replace the illuminate/html package with this:

"laravelcollective/html": "5.2.*"

Then in your config/app.php file, add this to your providers array:

Collective\Html\HtmlServiceProvider::class

and this to your aliases array:

'Form' => Collective\Html\FormFacade::class,
'Html' => Collective\Html\HtmlFacade::class,

The docs can be found here: https://laravelcollective.com/docs/5.2/html

Look at this
https://laracasts.com/discuss/channels/laravel/call-to-undefined-method-illuminatefoundationapplicationbindshared

Quote "bindShared has been renamed to $app->singleton()"

[Edit] I think you have something is your own custom code what need to be changed from : $this->app->bindShared() to: $this->app->singleton().
