ASP.NET Core pipeline, C# 14, and .NET 10 networking
A varied .NET roundup covering filters, middleware, dependency injection, testing, logging, LINQ performance, and new platform features.
Jasen's top three picks
- 1 ✨ Unlocking ASP.NET Core Filters — Mastering the Request Pipeline
Medium
Filters are the right kind of sharp tool when you need pre/post action logic without polluting controllers.
- 2 The Practical Guide to ConfigureAwait(false) in 2025 — Stop Using It Blindly
Medium
The ConfigureAwait(false) piece is a good reality check; this one’s more nuanced than old blog-post cargo cult.
- 3 .NET 10 Networking Improvements
Microsoft Dev Blogs
If you care about the platform roadmap, the .NET 10 networking post is the most concrete update in the stack.
Editor's note
I kept this issue intentionally mixed: there’s practical ASP.NET Core plumbing, language updates, and platform news all in one pass. The .NET 10 networking post is a standout for folks tracking runtime and BCL changes, and the filters/middleware pieces are useful if you live in request pipelines. I also liked the C# 14 extension members article and the warnings-as-errors guidance for teams tightening up builds.
