API Performance, Agent Routing, Reliable Builds
Coverage spans ASP.NET Core tuning, xUnit testing, agent memory and routing, auth reuse, service discovery, and locked dependency graphs.
Jasen's top three picks
- 1 xUnit: The Modern .NET Unit Testing Framework
medium.com
A solid xUnit refresher for newer teams and a handy baseline if you're standardizing test structure across services.
- 2 Undo Is a Feature: Saga Compensation and the Reconciliation Backstop
medium.com
Good reminder that distributed workflows need a plan for failure after the happy-path transaction is long gone.
- 3 5 Ways to Improve ASP.NET Core Web API Performance with a Real-World Example
c-sharpcorner.com
Concrete performance advice that maps well to the bottlenecks most API teams actually hit first.
Editor's note
I kept this one intentionally mixed, which is usually where the most useful reading stacks up. The ASP.NET Core Web API performance piece is practical and grounded in changes teams can apply quickly, while the reproducible builds article gets into dependency control work that pays off long after release day. I also liked the pair of agent-focused entries on memory and sandboxed code execution because they push past basic AI demos into architecture decisions.
