Windows UI Library 2.2 Official Release
AUGUST 2019
New Features
TabView
Description
The TabView control is a collection of tabs that each represents a new page or document in your app. TabView is useful when your app has several pages of content and the user expects to be able to add, close, and rearrange the tabs. The new Windows Terminal uses TabView to show multiple command line interfaces.

NavigationView Updates
a) NavigationView's Back Button update
Description
In NavigationView's minimal mode, the back button no longer disappears. When opening and closing the pane, users no longer need to move their cursor to click the hamburger button. This feature will work by default. You don't need to make any code changes to make this work.
b) NavigationView - No Auto Padding
Description
App developers can now reclaim all pixels within their app window when they use the NavigationView control and extend into the title bar area.
