Editor's note
I put together another intentionally mixed lineup today, and a few items stood out right away. The EF Core 11 split query improvement is the sort of practical runtime win people can use immediately, while the API key authentication guide does a nice job covering production concerns instead of stopping at a demo. I also liked seeing MAUI move to CoreCLR in .NET 11 and the post on designing for partial failure, because both point at architectural decisions that matter long after the first deploy.
