Xamarin Hot Reload 1
XAML Hot Reload for Xamarin.Forms enables you to make changes to your XAML UI and see them reflected live, without requiring another build and deploy.
XAML Hot Reload for Xamarin.Forms speeds up your development and makes it easier to build, experiment, and iterate on your user interface.
And this means that you no longer have to rebuild your app each time you tweak your UI - it instantly shows you your changes in your running app!
