Editor's note
I curated a pretty classic mixed bag today: some C# fundamentals, some ASP.NET Core, and a bit of tooling and security. Khalid’s cookie chunking write-up is the kind of practical web detail that saves debugging time, and the Visual Studio extensibility piece is useful if you build around the IDE itself. I also liked the BenchmarkDotNet article for keeping performance work grounded in measurement rather than guesswork.

Letter from the editor:
Hi all, we've been steadily growing and I've been spending a ton of time to help automate and curate new sources. Last week we added 5 new great .NET blogs to our source list, and more importantly, launched our new website. Check it out:
The big change is that you can now access all of our historical newsletters directly as I've integrated the site with our newsletter provider. I’ve also spent some more time trying to format these emails so they work for all platforms. Oh MS Outlook, how I loathe you…
Hope everyone has a great week.

Jasen's take on today's picks

A nice reading list if you’re filling gaps in C# fundamentals or looking for a refresher on scope, generics, and ref/out.
.NET Core CLI: The Ultimate Command-Line Companion
Practical ASP.NET Core coverage here: cookie chunking, basic auth, and Razor productivity are all immediately relevant.
ASP.NET Core and Chunking HTTP Cookies
BenchmarkDotNet and Copilot round out the issue with one post about measuring code and another about generating boilerplate.
The Visual Studio extensibility runtime piece is a good reminder that tooling work lives close to the platform changes it depends on.
