Windows 8 Snap View

Windows 8 Snap view is the process by which two apps can be displayed, or docked, side-by-side in Windows 8. These apps can consists of two Metro-style apps or one Metro style app and one legacy Windows app. The Snap View, takes up 320 pixels of the on-screen real estate, while the rightmost app takes up the rest.

When developing a Windows 8 Metro app you are required to cater for Snap view if you wish to submit your app to the Windows 8 app store.
