- 3 Difference Between Abstract Class and Interface in C#
C# Corner
Classic C# fundamentals, but with enough detail to be useful for juniors and seniors alike.
Editor's note
I kept this issue deliberately mixed, from core C# refreshers to newer tooling and data work. The pgvector piece is especially practical if you want vector search without introducing a separate database, and the security article is a good reminder that exceptions can leak more than you think. The Claude Code session breakdown is also worth a look for anyone following agent workflows.
