Everyone here missing some the main features of modern dotnet: cross-platform by default with the new runtime, CoreCLR (no more Mono).

Additionally, blazingly fast, especially as they continue to use stronger memory-aware primitives like Span<T> under the hood, and back that work with code in System.Numerics that continues to lean into hardware intrinsics.

C# itself is also an incredible language, much maturing since .NET 4. Things like Source Generators, record types, collection expressions... you can be _nearly_ as terse as something like python but with all the added benefit of C#'s type system (AND you get LINQ!).

People act like C# is some weird hanger-on dinosaur of a previous age of "tech" that people hang on to out of stubbornness, but IMO it's one of the most forward thinking languages today with an incredibly powerful runtime to boot.
