    > I do think C# is by far the best mainstream language

C# is a hugely underrated language that I feel like often gets overlooked when teams look to move beyond JS/TS. The language has a pretty tight syntactic congruency to JS/TS[0], Entity Framework is pretty amazing in terms of DX/perf/maturity, and it seems like we should see more C#/.NET it in the wild than we actually do.

My sense is that there are some legitimate reasons to pick something like Kotlin (JVM ecosystem), but a lot of folks that might have worked with C# in passing in the .NET Framework days simply haven't given the ecosystem another look. It's productive, stable, performant, and secure.

VS Code support is really good and Rider has a community license available.

JVM probably has a better ecosystem, so Kotlin wins in that regard. I would also say there's a huge and painful difference between C# and TypeScript, which is that C# has nominal typing (no equivalency between types unless they're literally the same) and TS has structural/duck typing (if the members of two objects are the same, they're equivalent).

That makes sense because C# can be much lower level and has its own set of priorities during compilation, so I'm not really complaining. But ergonomically, you really miss the TS type system when you don't have it.

We're not there yet, but if you squint, named tuples kinda interesting because it's also shape-based: https://www.reddit.com/r/csharp/comments/164w8l1/how_do_yall...
