EF Core, ASP.NET Auth, AI Agents, MAUI CoreCLR
Covers split query speedups, API key auth, Kafka event handling, Azure Functions, SignalR tracking, MAUI CoreCLR, and Blazor Web Workers.
Jasen's top three picks
- 1 Removing byte array allocations using ReadOnlySpan
csharpdigest.net
A clean reminder that small allocation cuts still matter, and ReadOnlySpan remains one of the best tools for low-level hot paths.
- 2 Three Ways to Handle Multiple Event Types in a Kafka Topic Using .NET, Avro, and Schema Registry
medium.com
Useful if you're balancing topic design against schema evolution and consumer complexity in Kafka-heavy systems.
- 3 How .NET Developers Transition Into Software Architecture (Without Rewriting Everything)
medium.com
A pragmatic architecture piece that avoids the usual rewrite fantasy and focuses on how teams actually grow responsibilities.
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.
