Wersja referencyjna zestawu System.Web.Helpers w projekcie nie może b e pasujące do wersji wspomnianej w pliku web.config. Wykonaj poniższe kroki.

  1. Sprawdź wersję odniesienia System.Web.Helpers.
  2. Sprawdź plik web.config w katalogu głównym aplikacji WWW i sprawdź, czy jest wpis dla System.Web.Helpers i sprawdź, czy jest on zgodny z wersją referencyjną.
  3. Sprawdź plik web.config w folderze "Widoki" aplikacji WWW i sprawdź, czy jest wpis dla System.Web.Helpers i sprawdź, czy jest on zgodny z wersją referencyjną.

Miałem ten problem. Powodem było dodanie widoku Żyletki do projektu Web Forms. Z powodu tej akcji Visual Studio zostało dodane do wersji .Net w wersji 5 i wprowadziło wiele innych modyfikacji do projektu.

Naprawiłem problem, przechodząc w Solution Explorer > Pending Changes. Obserwowałem całą listę nietypowych plików na liście. Kliknąłem dowolny plik i kliknąłem na numer Source Control > Undo Pending Changes. Wybrałem nietypowe pliki i Undo Changes i po odbudowaniu zostało naprawione.

Widziałem te dodatkowe pliki, które zostały dodane (bez widocznego) powodu również w innych przypadkach. Jakaś rzecz whack-a-doodle Visual Studio robi z powodów, które nie są dla mnie jasne.
