.NET: Avoid Using Guid.CreateVersion7
- sdrapkin 11mo agoGuid.CreateVersion7 in .NET 9+ claims RFC 9562 compliance but violates its big-endian requirement for binary storage. This causes the same database index fragmentation that v7 UUIDs were designed to prevent. Testing with 100K PostgreSQL inserts shows rampant fragmentation (35% larger indexes) versus properly-implemented sequential GUIDs.
