ASP.NET Core, AI agents, and performance
Practical ASP.NET Core coverage: rate limiting, authentication, health checks, Redis, Polly, and performance tuning, plus AI agent and database tips.
Jasen's top three picks
- 1 How to use ShowColumns() Function in Power Apps
C# Corner
ShowColumns is a handy reminder that small Power Apps choices can improve app shape and data flow.
- 2 PostgreSQL 18 Performance Tuning for EF Core Applications
C# Corner

- 3 How to fix if My BIOS corruption on PC?
Microsoft Tech Community
Rate limiting belongs in more ASP.NET Core apps than people admit; this walks through the protection layer well.
Editor's note
I curated a mixed issue with a lot of practical ASP.NET Core work, plus AI agent tooling and database tuning. The rate limiting, passkeys, and health check pieces stand out because they solve real production problems, while the PostgreSQL 18 and Redis articles are useful for squeezing more out of apps. I also kept the newer AI agent and Semantic Kernel posts in the lineup because they show where .NET is headed without losing sight of day-to-day engineering.
