Я пишу приложение на C # с использованием SQL Server CE. Evrtting прекрасно работает, и теперь я получаю следующее исключение: " Инициализатор типа для 'VideoStoreManager.AppData.DataBaseManager' вызвал исключение. " для этой строки кода: DataBaseManager.Connection.Open ();
Вот и все исключение:
System.TypeInitializationException was unhandled
Message="The type initializer for 'VideoStoreManager.AppData.DataBaseManager' threw an exception."
