Note:
* Use the app bar
Use the app bar to display commands to users on-demand. The app bar shows commands relevant to the user’s context, usually the current page, or the current selection.
* Use context menus
You can use context menus for clipboard actions (like cut, copy, and paste), or for commands that apply to content that cannot be selected (like an image on a web page).
* Use the charms
Leverage the charm and app contracts to enable common app commands. Avoid duplicating app contract functionality on your app’s canvas or in the app bar.
/ Search: Let your users quickly search through your app’s content from anywhere in the system, including other apps. And vice versa.
/ Share: Let your users share content from your app with other people or apps, and receive shared content.
/ Devices: Let your users enjoy audio, video, or images streamed from your app to other devices in their home network.
/ Settings: Consolidate all of your settings under one roof and let users configure your app with common mechanism they’re already be familiar with.
* Use the canvas
Users should be able to complete the core scenarios just by using the canvas. Whenever possible, let users directly manipulate the content on the app’s canvas, rather than adding commands that act on the content.
For example, in a Restaurant browsing app, finding and viewing restaurant details should be done on the canvas by tapping, panning, or selecting content.
