Windows Store Apps quick tip: getting the app version number

If you need to get the version information of your app from code, the details you want resides in Windows.ApplicationModel.Package.Current.Id.Version.

For example, to get a full version string you could use the below code:

string.Format("{0}.{1}.{2}.{3}", Windows.ApplicationModel.Package.Current.Id.Version.Major, 
                                 Windows.ApplicationModel.Package.Current.Id.Version.Minor, 
                                 Windows.ApplicationModel.Package.Current.Id.Version.Build, 
                                 Windows.ApplicationModel.Package.Current.Id.Version.Revision)

That is all.
