AppBar in Windows Store App

I have a goal for year 2013. Learn something new everyday. Or at least try to learn. Alright, may be not on the weekend or the days I am booked with meetings. 

Today, I learn about app bars in Windows Store apps.

Points to remember:

1. App bar can sit at the top or bottom of a page
2. We can launch app bars using WIN+Z key or using mouse in that area or swiping on touch devices
3. Page.TopAppBar and Page.BottomAppBar XAML tags of a page are used to set the app bar.
4. AppBar XAML tag is used to create an app bar.

My detailed article on AppBar will be coming soon.
