Информация о версии: Microsoft .NET Framework Версия: 2.0.50727.5446; ASP.NET Версия: 2.0.50727.5420

Развернутая сборка AutoMapper создана для .NET 4.0:

«Эта сборка собрана средой выполнения, более новой, чем загруженная в данный момент среда выполнения, и не может быть загружена».

Это не будет работать вместе. Вероятно, вы можете исправить это, переключив пул приложений на .NET 4.0.

Попробуйте изменить AppPool… Щелкните правой кнопкой мыши на вашем приложении в IIS, Управление приложением => Дополнительные настройки => пул изменений. asp.net пул v4 работал у меня…

Проверьте ссылку на библиотеку DLL AutoMapper — возможно, она неправильная. Возможно, вам придется удалить его и добавить обратно.
