Я пытаюсь использовать NHibernate для моего MySQL, но у меня все еще есть проблема с подключением к моей базе данных localhost.
Исключения:
MySql.Data.MySqlClient.MySqlException
HResult=0x80004005
Message=Unable to connect to any of the specified MySQL hosts.

Конфигурация находится в ~/bin/debug, и Nhibernate может видеть ее, но по-прежнему не может подключиться к базе данных.
