Editor's note
I pulled together a pretty classic mixed bag today: Blazor, language features, performance, and a few AI-related pieces. The custom 404 page in Blazor Web Apps and the EF Core performance guide stood out because they’re immediately practical for shipping apps. I also liked the MediatR replacement write-up and the .NET 10 preview coverage for anyone tracking what’s next.
