Why doesn't intellisense work in Visual Studio?

Question

PHP

XAML autocomplete in Xamarin Forms doesn't work for me and constantly underlines error on unrecognized elements. Is this normal for Visual Studio or do I need to be shamanic in the settings?

Answer 1

If you just display the code, then you can

$str = file_get_contents('https://www.rbc.ru');
$html = htmlspecialchars($str);
echo $html;

Answer 2

Solved the problem by installing ReSharper
