Jasen's top three picks
- 1 Prompt Engineering — Self-Consistency, Direct Stimulus & ReAct

A practical look at prompt techniques, not just buzzwords.
- 2 How to Demonstrate Deep C# Knowledge: A Guide Through Delegates and Events

Good refresher on delegates and events for interview prep or real-world code reviews.
- 3 Upgrade to modern .NET with GitHub Copilot: Assess → Plan → Execute

Editor's note
I pulled together a deliberately mixed lineup this time: AI-assisted modernization, core C# craft, performance work, and data/platform articles. The Copilot upgrade walkthrough is useful if you’re planning a legacy-to-modern .NET move, and the deep dive on delegates and events is a solid senior-level refresher. I also liked the idempotency piece because it gets past the theory and into the real failure modes we see in production.
