  • Feature switching (basically feature flagging) via AppContent.TryGetSwitch and some minor changes in the .csproj file.
  • LINQ methods such as AggregateBy() and CountBy()
  • Support methods such as Span.Split() and IDictionary.GetAlternateLookup<T>()

  • Hybrid cache where you can use distributed and in-memory caches.
  • JSON schema support via GetJsonSchemaAsNode().
  • GUID version 7 support via Guid.CreateVersion7() where the GUIDs are ordered sequentially
