Remarks
The SqlPersistenceProviderFactory class represents a factory class for a fully-functional, durable service persistence provider. You can use this system-provided provider to persist and retrieve state information about a durable WCF service.
In addition to persistence, the provider created by the SqlPersistenceProviderFactory class implements locking of service state data records by inheriting from the abstract LockingPersistenceProvider class. Methods that interact with persisted data (such as Create or Update) have an optional parameter (lockInstance) that defines whether locks on the data in question are released or maintained.
Note
PersistenceException exceptions thrown by SqlPersistenceProviderFactory do not have their exception details hidden by default. To protect against security vulnerabilities, these details can be hidden by setting IncludeExceptionDetailInFaults to false.
Note
The SQL Persistence Provider stores and retrieves data from a SQL Server database. The host must create a secure SQL Server environment to protect against attackers gaining read/write access to the instance state either in the database or on the wire between the application and the database.
Constructors
| SqlPersistenceProviderFactory(NameValueCollection) |
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified parameter collection. |
| SqlPersistenceProviderFactory(String, Boolean, TimeSpan) |
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string, |
| SqlPersistenceProviderFactory(String, Boolean) |
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string and |
| SqlPersistenceProviderFactory(String) |
Initializes a new instance of the SqlPersistenceProviderFactory class, configured with the specified connection string. |
Properties
| ConnectionString |
Gets the connection parameters for persistence provider instances created with this factory. |
| DefaultCloseTimeout |
Gets the default time-out value used when persistence providers created with this factory are closed. |
| DefaultOpenTimeout |
Gets the default time-out value used when persistence provider is opened. |
| IsDisposed |
Gets a value that indicates whether the communication object has been disposed. (Inherited from CommunicationObject) |
| LockTimeout |
The time-out for lock ownership used by persistence provider instances created by this instance. Locked instances are automatically unlocked after this time period. |
| SerializeAsText |
Specifies whether data is serialized as text rather than binary in persistence providers created with this factory. |
| 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
| Abort() |
Causes a communication object to transition immediately from its current state into the closing state. (Inherited from CommunicationObject) |
| BeginClose(AsyncCallback, Object) |
Begins an asynchronous operation to close a communication object. (Inherited from CommunicationObject) |
| BeginClose(TimeSpan, AsyncCallback, Object) |

| BeginOpen(TimeSpan, AsyncCallback, Object) |
Begins an asynchronous operation to open a communication object within a specified interval of time. (Inherited from CommunicationObject) |
| Close() |
Causes a communication object to transition from its current state into the closed state. (Inherited from CommunicationObject) |
| Close(TimeSpan) |
Causes a communication object to transition from its current state into the closed state within a specified interval of time. (Inherited from CommunicationObject) |
| CreateProvider(Guid) |
Initializes a new LockingPersistenceProvider instance that uses a SQL database as its persistence store. |
| EndClose(IAsyncResult) |

| Open() |
Causes a communication object to transition from the created state into the opened state. (Inherited from CommunicationObject) |
| Open(TimeSpan) |
