That's a lot of goodies in a new release! It seems it is outpacing the JVM's development...

Apart from [the equivalent of] records, I see nothing big. Except... this '''let! a = fetchA() and! b = fetchB()''' really puzzles me. Does C# have a high-level syntax for concurrency timing? [something that Java is strongly lacking, and that Typescript did solve with Promise.all(), which is an ugly syntax, from my perspective] Any elaboration on this is very welcome.

The inlining and escape analysis changes are fairly big from a performance perspective.

Also, C# doesn't need nearly as many massive changes like project Valhalla because they got a lot of those design choices right from day 1 (mostly by looking at what Java did that was dumb and avoiding it).

For us, every .NET upgrade since .NET 5 has gone surprisingly smoothly and reduced CPU/RAM usage by 10–15%. We were even able to downgrade our cloud servers to smaller instances, literally. I wish .NET was more popular among startups, if only C# could get rid of the "enterpisey" stigma.

The XML/config side of things just isn't for everyone. Sometimes Go's simplicity wins out.

Do you also make everyone wear the same clothes, drive the same vehicle, order the same food

> Do you also make everyone drive the same vehicle

Good analogy. If, say, your organisation maintains a fleet of cars - it needs to keep them on the road, get them serviced, replace parts, refresh individual cars regularly etc.

How many different makes and models do you support? A small org might decide that it only makes sense to support one. A larger org might have the resources for 3 or 4, so that there is 1 or 2 "general purpose" models, and then other ones suited to specialised tasks.

No, that's not true. If you share code like this then you can do things like put the same validation code in the frontend and the backend: frontend to give a nice user experience, and backend to protect the endpoint.

OpenAPI does support patterns for fields and nullables/non-nullables - that already gets you very far regarding validation. A decently sophisticated generator (which don't exist IMHO) would generate the validation code for your respective language.

True, but you can get all the way to zero duplication if you write it directly and share that code.

It is as simple as what you get with Cargo, and possibly even more readable.

.NET, unlike Go, has all needed management commands built into its CLI too: dotnet new {template}, dotnet add/remove package, dotnet sln add/remove, etc.

Vault, Keycloak, Flink are language agnostic or there exist bindings for most popular languages. Documentation is vastly better compared to Java ones, it's like day and night, LINQ is vastly superior to anything that Java offered - but i haven't used java in a very long time. And every time i had to write java it felt like i went backwards in time by 5-10 years. If i remember right Java's webserver beats ASP.NET in p…

>If i remember right Java's webserver beats ASP.NET in performance benchmarks That's not the case anymore. Kestrel is one of the fastest servers there is, and it beats every Java server out there.

I do not have any benchmarks other than this[1] to refer to, but I work with Quarkus[2] and Java 25 LTS (just recently released) services deployed on AWS EKS and we are very happy with the performance (for mobile game backends)

How is it so different than Visual Studio that you think it is "better"?

I've used Rider for several years now on and off. Generally I would put these at the top of the list. - Integrated ReSharper. - Far better performance (it isn't even close) - Doesn't take 30GB of disc space up. Visual Studio has been a massive disc space hog since forever. Rider is a few hundred megabytes IIRC. - Less bugs (Visual Studio has been progressively getting worse). - There was better tooling IMO around NuG…

>- Less bugs (Visual Studio has been progressively getting worse).

Eeeeeeh...it's not quite roses and rainbows on the Rider side either, and that's coming from a Jetbrains fanboy. (Although admittedly, I'm not really up-to-date on the current state of VS in day-to-day work)

But yeah, the coding/refactoring support (Resharper et al) and general quality and integration of tooling (database tools, package managers, version control, debugging (esp. multi-process) etc.) is the big one for me.

Is it though? Backends can be any language and there's a lot more variety there -- TS+node, Go, Python, Java. It's just .NET that's largely ignored for no real technical basis.

> It's just .NET that's largely ignored for no real technical basis. As someone who has been developing primarily on .Net for the past decade this is absolute bullshit. 1. It’s only very recently that .Net became open source. Until then you would frequently hit issues where the only option was to rely on the few support calls you got with MS engineers with your $1000+ Visual Studio subscription to move forward. And b…

.Net is also good as a platform for other languages. I recently started working with RemObjects, and you can compile languages like Java, Swift, Go and more (VB, Pascal) to .Net. Then, the whole framework and ecosystem is available. I'm liking it a lot. They have customers who are startups and the 'got to have tools' folk like having lots of languages since they can onboard people who know anything-not-C# and benefit…

It's bad enough when you've got constantly changing "best practices" from MS so the thing you wrote last year doesn't look anything structurally like what you're doing now.

And all the 6-month-old on-line docs and tutorials aren't only useless, but time wasting.
