A new way to edit your app settings
As part of the recent changes to the Windows Phone SDK, Microsoft has kindly added a user interface for editing your app’s manifest file.
Back in Windows Phone 7/Visual Studio 2010 days, when you wanted to define the capabilities your app required, or make other configuration changes, you had to edit the XML directly in the WMAppManifest file.
The Windows Phone 8 SDK now includes a nice little manifest designer, which is not only a nice touch, but pretty much required now that there is a raft of new properties that you can set.
Double clicking the WMAppMenifest file in your Visual Studio project will automatically open the manifest designer, instead of the XML source. The various settings in the manifest are available from one of the tabbed sections of the manifest designer.
