.NET 10

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.

Start-ups should strongly consider F#.

It's a force multiplier when you have a small team of strong developers.

>startups should consider niche language with extremely limited hiring pool.

sure, but only if you're doing something that actually demands it - and actual innovation - instead of usual 'lets repackage XYZ as SaaS and growthhack' strategy.

F# is less popular, but it’s a first class .Net language with full MS support and integration onto .Net (VM and ecosystem). C# has been tracking F# and aiming for language parity for years (ie all your modern C# devs should be learning the same language facilities). F# is multi-paradigm so C# devs can write idiomatic C# with minor forced changes. And as a .Net language you can always decompile it into C# and keep going from there.

That’s a radically different proposition than, say, raw OCaml and not particularly niche. It also impacts hiring pools differently since competent functional C# devs are viable, but it tends to appeal to a certain calibre of dev.

Moving faster with fewer errors and more talented candidate pool are relevant to repackaged SaaS startups too. Leaves more time for the other stuff and scales better.

don't get me wrong - i want F# features in C#! I like the ecosystem and both languages.

I'm just pointing out that no matter how cool the language is if it doesn't serve business needs(hiring, onboarding ,ease of replacing staff, target market) it won't be picked.
