SqlPersistenceProviderFactory.CreateProvider(Guid) Method

Definition

Namespace:

System.ServiceModel.Persistence

Assembly:

System.WorkflowServices.dll

Initializes a new LockingPersistenceProvider instance that uses a SQL database as its persistence store.

public:
 override System::ServiceModel::Persistence::PersistenceProvider ^ CreateProvider(Guid id);

public override System.ServiceModel.Persistence.PersistenceProvider CreateProvider (Guid id);

override this.CreateProvider : Guid -> System.ServiceModel.Persistence.PersistenceProvider

Public Overrides Function CreateProvider (id As Guid) As PersistenceProvider

Parameters

id

Guid

The unique identifier of the persistence provider being created.

Returns

PersistenceProvider

A newly-created PersistenceProvider.

Examples

The following code example shows how to execute the CreateProvider method. Note that the resulting provider is accessed as a LockingPersistenceProvider instance.

SqlPersistenceProviderFactory factory = new SqlPersistenceProviderFactory(
    DataBaseConstants.ConnectionString,
    false,
    TimeSpan.FromSeconds(60));
LockingPersistenceProvider provider = (LockingPersistenceProvider)factory.CreateProvider(Guid.NewGuid());

Remarks

The initialized persistence provider uses the current parameters of the creating factory (ConnectionString, LockTimeout, and SerializeAsText), even if the factory's parameters are changed after the persistence provider is created.
