Xamarin forms 3.3.0

The most recent release to Xamarin.Forms is the version 3.3.0. Since the Xamarin forms source is available, people have worked hard to recover and remove all the issues as well as bugs related to its previous versions.

Page Loaded by Highest Memory Usage
Grid Page Xamarin Forms 268,387,112 bytes
Grid Page Glidex Forms 16,484,584 bytes
View cell page Xamarin Forms 94,412,136 bytes
View cell page Glidex Forms 12,698,112 bytes
Image cell page Xamarin Forms 24,413,600 bytes
