Get the application version from the Package.appxmanifest in WinRT

If you want to get the version of your Windows 8 / WinRT application in code, you can use this method:

public static string GetAppVersion()
{

Package package = Package.Current;
PackageId packageId = package.Id;
PackageVersion version = packageId.Version; return string.Format("{0}.{1}.{2}.{3}", version.Major, version.Minor, version.Build, version.Revision);

}

This will ge the version from the application manifest file (Package.appxmanifest). This version is also used when submitting your application to the Windows 8 store.
