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 Службы Integration Services runtime.
Безопасность многопоточности
Любые открытые статический (Shared в Visual Basic) элементы этого типа потокобезопасны. Потокобезопасность с элементами экземпляров не гарантируется.
