SequentialGuidValueGenerator SequentialGuidValueGenerator Class

Generates sequential System.Guid values using the same algorithm as NEWSEQUENTIALID() in Microsoft SQL Server. This is useful when entities are being saved to a database where sequential GUIDs will provide a performance benefit. The generated values are non-temporary, meaning they will be saved to the database.
