C# is a very highly underrated (and oft misunderstood) language that has become more terse as it has aged -- in a very good way. C#'s terseness has not come at the cost of its legibility and in fact, I feel like enhances it in many cases.

This is also a highly underrated aspect of C# in that its surface area has largely remained stable from v1 (few breaking changes (though there are some valid complaints that surface from this with regards to keyword bloat!)). So the historical volume of extremely well-written documentation is a boon for LLMs. While you may get out-dated patterns (e.g. not using latest language features for terseness), you will not likely get non-working code because of the large and stable set of first party dependencies (whereas outdated 3rd party dependencies in Node often leads to breaking incompatibilities with the latest packages on NPM).

Often overlooked with C# is its killer feature: productivity. Yes, when you get a "batteries included" framework and those "batteries" are quite good, you can be productive. Having a centralized repository for first party documentation is also a huge boon for productivity. When you have an extremely broad, well-written, well-organized standard library and first party libraries, it's very easy to ramp up productivity versus finding different 3rd party packages to fill gaps. Entity Framework, for example, feels miles better to me than Prisma, TypeORM, Drizzle, or any option on Node.js. Having first party rate limiting libraries OOB for web APIs is great for productivity. Same for having first party OpenAPI schema generators.

Less time wasted sifting through half-baked solutions.

    > Code size shrank substantially, massively improving maintainability. As far as I can tell, most of this savings was just in the elimination of ECS boilerplate.

C# has three "super powers" to reduce code bloat which is its really rich runtime reflection, first-class expression trees, and Roslyn source generators to generate code on the fly. Used correctly, this can remove a lot of boilerplate and "templatey" code.

I make the case that many teams that outgrow JS/TS on Node.js should look to C# because of its congruence to TS[0] before Go, Java, Kotlin, and certainly not Rust.
