Middleware, C# changes, and architecture
Coverage includes SAML and JWT auth, zero-copy C# techniques, rate limiting, Blazor refresh issues, idempotency, observability, and AI agent security.
Jasen's top three picks
- 1 Building AutoStack.Identity: A Zero-Dependency .NET 10 Library for SAML 2.0, JWT, and XML Signing
medium.com
Interesting identity-library write-up, especially the zero-dependency angle. Worth a look if you want SAML and JWT support without dragging in a large stack.
- 2 Understanding Middleware in .NET
yogeshhadiya33.medium.com
A solid refresher on how requests actually move through the ASP.NET Core pipeline. Good entry-level grounding that still matters in production apps.
- 3 From Structs to Strongly Typed Zero-Copy Views in C#
medium.com
This is the kind of lower-level C# article I like seeing: concrete language mechanics tied to memory movement and data modeling.
Editor's note
I kept this one nicely mixed on purpose: language evolution, web pipeline fundamentals, architecture, and a few practical performance lessons. The union types preview is the obvious attention-grabber, but I also think the zero-copy C# piece is worth your time if you care about low-level efficiency. On the application side, the Clean Architecture walkthrough and the idempotency article both stand out for teams building real services, not toy samples.
