Внедрение зависимости модели представления с помощью кинжала 2

У меня проблемы с внедрением зависимости в мою модель представления. Я продолжаю получать Невозможно создать экземпляр класса ....viewModel.UserProfileViewModel. Я пытался разобраться в этом вопросе. Любые предложения будут действительно оценены. Вот мой код. В других вопросах я видел, что это обычно вызвано наличием параметра в конструкторе модели представления, и создание фабрики должно решить проблему. но, похоже, это не сработало для меня. Я должен что-то упустить.

Спасибо!
