string indexName
)
Type Parameters

The entity type corresponding to the applicable database table.

Remarks
The database does not change to reflect updates from the DatabaseSchemaUpdater object until the Execute() method is called. When that method is called, all changes are submitted to the local database as a single transaction, including version updates. Using a single transaction helps the database maintain integrity, such as in cases where the user exits the application during an upgrade.
For information about using a local database in your Windows Phone application, see Local Database Overview for Windows Phone.
