ASP.NET Core, async traps, and .NET 10 updates
A varied .NET roundup with middleware, authentication, DI, async bugs, EF Core vs Dapper, Azure tips, and .NET 10 previews.
Jasen's top three picks
- 1 Middleware in ASP.NET Core — Explained Like You’re Coding Daily but Still Unsure What It Does
medium.com
A solid middleware refresher for anyone who knows the pipeline exists but still wants the mental model to click.
- 2 99% of C# Devs Miss This Async Bug — It Crashes Real Apps Silently
medium.com
Good warning shot on async mistakes; these are the sort of bugs that look harmless in code review and hurt in production.
- 3 ️ Using CSharpier Per-Solution in JetBrains Rider
rafee03.medium.com
Rider + CSharpier is the kind of practical tooling note I like: small setup, big consistency payoff.
Editor's note
I kept this issue deliberately mixed: fundamentals, tooling, data access, and a few forward-looking .NET 10 pieces. The async articles and the middleware explainer stand out because they tackle bugs and concepts that still trip up experienced teams. I also like seeing practical pieces on configuration and DI alongside the C# 14 and source generators coverage.
