SignalR scale out and C# performance
This issue covers Redis-backed SignalR scaling, C# performance tuning, ASP.NET Core middleware and DI lifetimes, plus CQRS, OOP, and readiness checks.
Jasen's top three picks
- 1 Scaling SignalR With a Redis Backplane
milanjovanovic.tech
SignalR scale-out is the kind of problem that looks easy until you add a second server.
- 2 The "Vibe Coding" Delusion: When AI Models and Rapid Tools Build Toys, Not Tools
c-sharpcorner.com
This AI critique is useful because it separates flashy demos from software that survives production realities.
- 3 How to Improve Performance in C# Applications

The performance guide is broad, but the real value is in reminding teams to measure before they optimize.
Editor's note
I picked a deliberately mixed lineup this time: some practical ASP.NET Core mechanics, some architecture refreshers, and a few AI and performance pieces. The SignalR backplane article stands out for anyone running real-time apps at more than one node, and the middleware plus DI lifetimes posts are solid reminders of the basics that still trip teams up. I also like the readiness-check article because it pushes health checks beyond the usual shallow “up or down” story.

SignalR connections are server-local. Scale out to multiple instances and messages stop reaching the right clients. Here's how the Redis backplane fixes that - and what you still need to get right.
