SequentialGuidValueGenerator SequentialGuidValueGenerator Class

Definition

Namespace:: Microsoft.EntityFrameworkCore.ValueGeneration Microsoft.EntityFrameworkCore.ValueGeneration

Assembly:: Microsoft.EntityFrameworkCore.dll

Edit

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.

Properties

GeneratesTemporaryValues GeneratesTemporaryValues

Edit

Gets a value indicating whether the values generated are temporary or permanent. This implementation always returns false, meaning the generated values will be saved to the database.
