Замечания
The IDbConnectionExtension interface enables you to implement an extension of the IDbConnection interface, which adds additional functionality for authenticating a connection to a data source. The IDbConnectionExtension interface can be used to build a custom data processing extension. For more information about Connection classes, see Реализация класса Connection для модуля обработки данных.
An application does not create an instance of the IDbConnectionExtension interface directly, but creates an instance of a class that implements IDbConnectionExtension.
Classes that implement IDbConnectionExtension must also implement all required members, and typically define additional members to add provider-specific functionality. Because IDbConnectionExtension inherits from IDbConnection, you must also implement all of the IDbConnection members as part of your Connection class including those members from IExtension.
