| LockingPersistenceProvider | The abstract base class from which all durable service persistence providers that implement locking are derived. |
| PersistenceException | This exception is thrown by a SqlPersistenceProviderFactory when general connectivity errors are encountered. |
| PersistenceProvider | The abstract base class from which all durable service persistence providers are derived. |
| PersistenceProviderFactory | The abstract class from which all durable service persistence providers must inherit. |
