Agentic QA, EF Core Encryption, ASP.NET Security
Coverage includes browser-driven agentic QA, AES-GCM field encryption in EF Core, OAuth with PostgreSQL, SignalR dashboards, DDD, and CSP hardening.
Jasen's top three picks
- 1 Building Agentic QA Pipelines with Browser Automation and .NET
C# Corner
A sensible pattern: let the model reason, but keep browser actions deterministic and testable.
- 2 Field-Level Encryption in EF Core: AES-GCM for PII Columns
Medium
Good, concrete security work. Column-level encryption is where a lot of teams eventually realize they needed more than TDE.
- 3 Managing Secrets in Microsoft Agent Framework
YapCast – Jesse Liberty
Secrets handling is still where many agent demos become real systems or real incidents.
Editor's note
I kept this one deliberately mixed, which is how I like the newsletter to read. The EF Core AES-GCM piece stood out because it gets practical about protecting sensitive columns instead of relying on broader database encryption alone. I also liked the agentic QA pipeline article for separating AI reasoning from deterministic browser execution, and the CSP nonce-vs-hash write-up is a useful security reality check.
