Из того, что я могу сказать от других постов, что я имею проблему с моей строкой подключения к база данных. Однако, я скопировал поставляемую строку подключения из AppHarbor и поместил ее в мой web.config.
До сих пор я только когда-либо запускал свое приложение на локальном хосте, и все всегда работало нормально. Может ли кто-нибудь указать какой-нибудь совет?
Похоже, что он пытается использовать простой поставщик данных, который обычно является локальной базой данных. Вероятно, вы не указали локальную базу данных – atbebtg
Можем ли мы увидеть ваш код initializeSimpleMembershipAttribute? (конечно, удалять любую идентифицирующую информацию) –
