Home Archive Async tricks, Identity, and .NET 10 RC 2 – .NET News Daily Issue #308 (Oct 21, 2025)

Editor's note

I curated a pretty classic mixed bag today: some practical ASP.NET Core pieces, some language fundamentals, and a few performance-focused reads. The .NET 10.0 RC 2 release is the anchor for release-watchers, while the async and GC articles are useful reminders that the runtime still rewards people who understand what’s happening under the hood.

Async tricks, Identity, and .NET 10 RC 2

Welcome to Tranquil Tuesday, where we take a pause from the chaotic churn and reflect on the elegant architecture of our code. As we stroll through the .NET landscape, it's time to peer under the hood and fine-tune our mental engine for precision and efficiency. Just like a classic car lovingly restored, today’s selection of articles promises to reignite your passion for craftsmanship and deepen your expertise. Ready to shift gears and explore some serious .NET know-how?
