While I can get the assembly version using the following code
var assembly = typeof(App).GetTypeInfo().Assembly;
var assemblyVersion = assemb
Here's what you can do to retrieve the version in code:
using Windows.ApplicationModel;
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);
}
