Observability, API Security, and AI Agents
Covers .NET 10 telemetry, ASP.NET Core auth and rate limiting, Semantic Kernel agents, Redis CRUD, LINQ structure, and C# language topics.
Jasen's top three picks
- 1 Convert DOCX to PDF in C#: 5 Methods Compared in 2026 - HackerNoon
hackernoon.com
Useful comparison piece if you need to balance library capability, output quality, and deployment constraints for document conversion work.
- 2 Observability in .NET 10 Using OpenTelemetry, Prometheus, and Grafana
c-sharpcorner.com
A practical monitoring stack article; worthwhile if you're wiring modern .NET telemetry beyond logs and basic metrics.
- 3 Understanding Builder Design Pattern in .NET
yogeshhadiya33.medium.com
Good refresher on a classic pattern that still helps when constructors start telling on your design.
Editor's note
I kept this one intentionally mixed, which is how I prefer the lineup when the community is publishing across every layer of the stack. The observability walkthrough for .NET 10 stands out because it connects OpenTelemetry to Prometheus and Grafana in a practical way, and the ASP.NET Core image analysis API is a solid production-minded build. I also liked seeing lower-level language pieces here, especially the covariance/contravariance explainer and the C# 14 static getter via extensions post.
