Я реализую Recycler View в своем проекте Xamarin Android и Card View

Я реализую RecyclerView и CardView. RecylerView не выдает никаких ошибок, но CardView xml показывает мне эту ошибку: Не удалось загрузить элементы управления из библиотеки поддержки Android. Это может исправить выполнение восстановления NuGet.

Я уже пробовал:

1. Восстановите пакеты NuGet.
2. Обновите все пакеты NuGet.
3. Bin и Obj удалить.
4. Построить и перестроить решение.
