If you you have AutomaticMigrationsEnabled = false; but have a dbo._MigrationHistory and the Model has pending changes EF throws a "The model backing the '' context has change since database was created" exception.
One would expect that if migrations were turned off that it wouldn't bother checking for the migration history to do the comparison.
