API Reliability, CQRS, Blazor AI, Aspire
Covers Web API anti-patterns, Redis caching, EF Core tuning, JWT refresh tokens, Aspire, OpenAI migration, and architecture validation.
Jasen's top three picks
- 1 Web API Anti-Patterns That Break Production Applications
c-sharpcorner.com
A practical checklist-style piece. These failure modes are common because they often look fine in development until traffic and retries show up.
- 2 Implementing CQRS and Mediator Pattern with MediatR in .NET Core
c-sharpcorner.com
Solid for readers still mapping CQRS to everyday .NET code instead of just architecture diagrams.
- 3 Diving in OOP (Polymorphism and Inheritance – Part 2)
c-sharpcorner.com
Good refresher material if you mentor juniors or want a clean way to explain override behavior.
Editor's note
I kept this one deliberately mixed, which is usually where the most useful issues land. The Web API anti-patterns piece and Andrew Lock’s write-up on automatic CSRF protection both hit real production concerns, while the EF Core performance article is the kind of tuning advice teams can apply immediately. I also liked seeing Aspire, MediatR/CQRS, and a couple of practical AI app pieces show up in the same lineup without forcing a theme.
