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.
