Remarks
In addition to persistence, the LockingPersistenceProvider class implements locking of service state data records. Methods that interact with persisted data (such as the Load method) have an optional parameter (lockInstance) that defines whether locks on the data in question are released or maintained.
Constructors
| LockingPersistenceProvider(Guid) |
When implemented in a derived class, creates a new instance of the LockingPersistenceProvider class, configured with the specified identity value. |
Properties
| DefaultCloseTimeout |
When overridden in a derived class, gets the default interval of time provided for a close operation to complete. (Inherited from CommunicationObject) |

When overridden in a derived class, gets the default interval of time provided for an open operation to complete. (Inherited from CommunicationObject) |
| Id |
Represents the Guid associated with this instance. (Inherited from PersistenceProvider) |
| IsDisposed |
Gets a value that indicates whether the communication object has been disposed. (Inherited from CommunicationObject) |
| State |
Gets a value that indicates the current state of the communication object. (Inherited from CommunicationObject) |
| ThisLock |
Gets the mutually exclusive lock that protects the class instance during a state transition. (Inherited from CommunicationObject) |
Methods

When implemented in a derived class, represents the beginning of the LoadIfChanged phase. The LoadIfChanged phase occurs when state data is loaded into the persistence provider from the persistence store and the state data in the persistence store has been changed. This method call does not lock the instance in the persistence store. |

When implemented in a derived class, represents the beginning of the LoadIfChanged phase. The LoadIfChanged phase occurs when state data is loaded into the persistence provider from the persistence store and the state data in the persistence store has been changed. This method call lets you specify whether you want to lock the instance in the persistence store. |

When implemented in a derived class, represents the end of the Delete phase. The Delete phase occurs when state data is permanently deleted from the persistence store. (Inherited from PersistenceProvider) |
| EndLoad(IAsyncResult) |
When implemented in a derived class, represents the end of the Load phase. The Load phase occurs when state data is loaded into the persistence provider from the persistence store. (Inherited from PersistenceProvider) |
| EndLoadIfChanged(IAsyncResult, Object) |
When implemented in a derived class, represents the end of the LoadIfChanged phase. The LoadIfChanged phase occurs when state data is loaded into the persistence provider from the persistence store, and the state data in the persistence store has been changed. (Inherited from PersistenceProvider) |
