Observability, deployment, and performance
Observability, Azure CI/CD, EF Core tuning, API security, AI agents, and .NET 10 file-based apps—practical reads for working developers.
Jasen's top three picks
- 1 ASP.NET Core Monitoring & Logging Mastery | Proactive Application Insights (Part-34 of 40)
c-sharpcorner.com
A solid observability primer that ties together logging, health checks, and App Insights before production pain does.
- 2 Deploy Azure Apps Automatically Using Azure Pipelines (YAML)
c-sharpcorner.com
A straightforward YAML pipeline walkthrough for shipping Azure apps without hand-driven release chores.
- 3 ⚡ One Trick To Improve EF Core Performance Using Query Splitting.

A small EF Core change with outsized impact: AsSplitQuery() can tame include-heavy queries in hot paths.
Editor's note
I put together a deliberately mixed lineup today: some production-hardened guidance, some framework history, and a few forward-looking pieces. The Application Insights and request smuggling articles stand out for real-world ops and security impact, while the EF Core and middleware posts are the kind of practical improvements you can apply right away.
