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You need to remove this outdated package (taken out of the core and no longer supported):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

Answer 2

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().

Answer 3

I solved it by the steps mentioned in Link1 Link2
After the upgrade please make sure all the Deprecations mentioned in Link2 are corrected in your current app. For me Illuminate\Contracts\Routing\Middleware had to be removed from all the Middlewares.
Also I had to install latest version of certain packages like "yajra/laravel-datatables-oracle": "~6.1.1",
