I do authorization through the services of "Vkontakte" but there is a code for Windows 8 version. The first problem appeared with Package.appxmanifest When adding an extension, there are problems ... How can this be fixed?

  • @Grundy is not exactly a mistake, it just does not allow adding this part of the code (Extensions, see screenshot) - Denisok
