Home Archive Lambda SnapStart for .NET and ORM pitfalls – .NET News Daily Issue #366 (Jan 9, 2026)

Editor's note

I put together a very mixed lineup today: cloud performance, data-access traps, and a few deep dives into core C# and ASP.NET Core mechanics. The SnapStart piece is especially useful if you’re fighting cold starts, and the EF Core async and mixed-mode ORM articles are good reminders that small data-layer choices can have outsized effects. There’s also practical performance content around Channels and custom queues for anyone tuning throughput.
