Parallel code, Redis caching, and EF Core
A varied .NET roundup on performance, ASP.NET Core caching and CORS, EF Core polymorphism, async internals, serverless design, and security.

- 1 Why Parallel Code Often Runs Slower

Parallelism can surprise you: more threads isn’t automatically more throughput.
- 2 Every Note-Taking App Tries Too Hard. I Fixed It.

A practical Redis caching guide, plus a separate cache stampede article that covers the nasty edge cases.
- 3 DotnetFastMCP: Enforcing Multi-Factor Authentication (MFA) for Critical AI Tools ️

MFA for AI tools is the sort of guardrail teams need before agents start doing real work.
Editor's note
I kept this issue deliberately mixed: performance, architecture, data access, tooling, and security all show up here. The parallel code piece and the cache stampede article are a good pair if you care about why “faster” code sometimes isn’t. I also liked the EF Core polymorphic relationships writeup and the MSSQL VS Code extension update because both are practical and immediately useful.
