Redis Channels and .NET 9 API Guidance
A varied .NET roundup with Redis messaging, API security, performance tips, new editor and agent tooling, plus C# fundamentals and .NET 9 coverage.
Jasen's top three picks
- 1 Publish–Subscribe Messaging in .NET 9 Using Redis Channels

Cursor-generated bugs is the kind of cautionary tale teams need right now.
Editor's note
I kept this issue deliberately mixed: Redis Channels and .NET 9 messaging sit beside editor experiments, API security, and practical language refreshers. The HybridCache piece and the performance-focused API articles are especially worth a look if you care about real-world throughput.
