Проблема конструктора XAML в VS2015

Привет всем, извините за мой английский, я итальянец, у меня проблема в течение 2 недель с дизайнером Visual Studio 2015, я программирую в Visual Basic для приложения Windows Phone 8.1 на платформе Windows 10, и дизайнер показывает мне следующую ошибку, и я не могу найти решение, эта проблема появляется, когда я создаю новое приложение Windows Phone 8.1 пустым (без silverlight), в то время как для всех остальных приложений дизайнер работает. Я заметил, что XDesProc.exe для этого типа приложений не запускается, в то время как он присутствует во всех других приложениях. Спасибо за вашу помощь
