Замечания
You create a managed connection manager by deriving a managed class from the ConnectionManagerBase, and then marking it with DtsConnectionAttribute attribute.
When creating a managed connection manager, you must ensure that the threading model is Both for the connection manager to work properly with the Integration Services runtime.
Безопасность многопоточности
Любые открытые статический (Shared в Visual Basic) элементы этого типа потокобезопасны. Потокобезопасность с элементами экземпляров не гарантируется.
