I'm not going to log in to Xitter to read the rest of his tweets, but it doesn't seem like Miguel regrets using C# or is particularly in love with Dart.

He's very complimentary of the goals and governance of Flutter, which is certainly more important than a language choice between two respectable languages.

I do think C# is by far the best mainstream language, but good IDE support and library ecosystem are the dealmakers/breakers for me when choosing a stack for a project.

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...

I think C# is just too associated to .Net like how Ruby is tied to Rails. Plus it's a Microsoft managed language, and if you're looking to move out of JS / TS, then you probably don't trust Microsoft's management of languages...

I mean, .NET is what makes C# so good. You also get to use F#, you get to target all these platforms and a very flexible deployment/compilation model for your applications - something that e.g. neither Go nor Java offer to the same extent.

There is also a greater selection of IDEs and LS's.
