https://t.co/aPL2NRaVm5 Core ranks among the top web frameworks for performance. In TechEmpower Round 23 it led popular ones in Fortunes with ~610k RPS, beating Go Fiber (~338k), Rust Actix (~320k), Java Spring (~244k), and Node Express (~78k). Current HttpArena shows minimal APIs strong vs Fastify/Gin/Spring. Multi-threaded Kestrel handles high concurrency well; tuned low-level options can edge it in pure throughput.

If you haven’t experienced C#, you have no idea how good it is.

[JSONB @vyrotek]

C# is pure dominance. Clean syntax that respects your time, features like LINQ and async that feel illegal, and .NET power that scales from Unity blockbusters to enterprise beasts. Other languages talk. C# ships.

Can’t believe the .net OSS drama again…

Yes, some free dependencies become paid and sometimes they disappear altogether

Deal with it

If your team can’t pivot away from a dependency in 2026, you have bigger worries

Seriously. It takes so much time and effort to really take full advantage of all this; you might as well just do it yourself.

Middleware, but for outgoing HTTP requests?

Yes, we have this in ASP .NET Core.

DelegatingHandlers allow you to add behavior around outgoing requests.

It's like a middleware, except it works in the opposite direction.

An excellent use case for this feature?

Adding authentication headers to the request. 👇

Here's how to implement this + 2 more use case for DelegatingHandler: https://t.co/LgaXCmU0uA

A classic from the golden era: Anno 1602 (created by Max Design in 1998).

It was a massive surprise blockbuster, both commercially and critically acclaimed. The game kickstarted what eventually turned into a franchise that is still alive today with its most recent release, Anno 117, from November 2025.

So, what made the first Anno game so great? For its time it showed incredible attention to detail: excellent graphics, a wonderful soundtrack, and above all a highly addictive “just one more minute” gameplay - seeing your empire grow through colonization and trade.

Other games such as Sim City or The Settlers had a similar vibe, that slow and steady progress, and sometimes just zooming out and looking at what you had created was reward enough. This was also true for Anno, simply looking at it, while life hustled and bustled by, was wonderful. Perfect for late night gaming sessions when reflexes and speed were not at peak anymore.

@davepl1968 our phone number hardcoded in a windows assert that shows up in every source leak
that's the most unintentional calling card in software history.

legends leave easter eggs and dave left his digits.

@mladenm This is very similar to an example of a property that goes out of the box. There are some assumptions about indexers or properties. On what to expect. Having an indexer with linear complexity is very dangerous in terms of of having very challenging perf issues in the future

Ported the excellent Uno Nebula SkiaSharp shader example by @mzikmunddev to my ImageSharp backend because my samples were rubbish. Very nice!
