DatabaseSchemaUpdater.AddIndex(Of T) Method
Adds a database index to a local database.
Assembly: System.Data.Linq (in System.Data.Linq.dll)
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.
