The most important thing that you need to consider for Metro style application is its manifest file. After you create a new project from Metro application you will find a file with appmanifest extension. This file represents an xml based manifest file which holds all metadata information about the application.
The application manifest file of Metro application defines the name of the application, its version, its logo, its tile size etc. It also defines about capabilities and declarations of the application or even defines the packaging and deploying settings.

The first tab shows the metadata information about the application, the second shows capabilities, then declarations and finally Packaging. We will discuss each of them separately.
You can easily choose your own settings from this IDE component and work on it.
