ASP.NET Core security, AI tools, and .NET 8 performance
This issue covers ASP.NET Core configuration, security, auth, health checks, AI feature design, source generators, and .NET 8 memory pitfalls.
Jasen's top three picks
- 1 What is a Vector Database in Data Science?
C# Corner
Vector databases are now table stakes for AI search and recommendations, and this primer is a useful grounding piece.
- 2 ASP.NET Core - How to Use appsettings.json and IConfiguration
C# Corner
appsettings.json and IConfiguration remain everyday tools; this one is a solid refresher for keeping configuration tidy.
- 3 The Package Version Chaos is Over: How .NET
Medium
Version mismatches are still painful in .NET, so a package-version cleanup story is worth reading if you’ve fought dependency drift.
Editor's note
I curated a very mixed lineup today: practical ASP.NET Core guidance, security hardening, and a few AI-heavy pieces. The Visual Studio 2026 Insiders post stands out for its IDE roadmap, while the unmanaged memory article is a good reminder that GC health does not guarantee container health. This issue also includes several fundamentals refreshers that still matter in real projects.
