Q:

Xamarin. Forms Hamburger Menu Icon gone after Update to Xamarin. Forms 2.2

After I updated my Xamarin. Forms project from Xamarin. Forms 2.0 to Xamarin. Forms 2.2, the Hamburger Icon is gone.  
I've googled without luck, has anybody experienced the same issue? 

A:

If the default icon has disappeared you can set your own icon of the Master page for example:
public class MasterPage : MasterDetailPage
{
    FlyOutMenuPage menu = new FlyOutMenuPage ();
    Master = menu;
}

public class FlyOutMenuPage : ContentPage
{
    Icon = "menu.png";
} 

And menu.png is a resource image, you can get lots of icon from here:
