An easy-to-learn, statically typed language that can scale to near-native performance with Native AOT and low-level features, though critics say it keeps piling on features and complexity.

Why people recommend it

Each mark is one comment

  • Fast with low-level performance tools

    “There's been a really solid effort by the maintainers to improve performance in C# , especially with regard to keeping stuff off the heap.”

    Comment from 25 Nov 2025 in “Bytes before FLOPS: your algorithm is (mostly) fine, your data isn't”

    “C# is good in that it's "easy" yet the performance profile of the features allows optimized code to run far closer to C++/rust/etc”

    Comment from 21 Oct 2026 in “C# now beats Rust on WASM size”

    “It has both generic vector types across a range of sizes and a good set of intrinsics across most of the common instruction sets”

    Comment from 5 Nov 2025 in “The state of SIMD in Rust in 2025”
  • Steady stream of useful features

    “Reified generics, value types, nullable reference types, LINQ are only some of the things that would give C# an edge in DevEx today.”

    Comment from 12 Apr 2026 in “High-Level Rust: Getting 80% of the Benefits with 20% of the Pain”

    “The language design team is really making sure that the features work well throughout and I think that does deserve some credit.”

    Comment from 8 Apr 2026 in “Explore union types in C# 15”

    “Where C# has had object initialisers and pervasive IEnumerable with a very simple interface that nearly everything uses.”

    Comment from 12 Nov 2025 in “.NET 10”
  • Easy to learn and productive

    “C# does it really well because if your problem isn't performance/memory-constrained, you can ignore these features and fallback on the language's natural ease of use.”

    Comment from 23 May 2026 in “dotNET (OK, C#) gets union types”

    “Everything just kind of worked the way I expected it to. There are sharp edges, but far fewer than expected and always for an actual reason.”

    Comment from 7 Dec 2025 in “Perl's decline was cultural”

    “I can onboard an average developer that's familiar with Typescript and have them be productive in C# in a week.”

    Comment from 5 Apr 2026 in “Lisette a little language inspired by Rust that compiles to Go”
  • Native AOT compilation

    “C#, with default tooling, can compile without needing a VM, for windows, macOS, linux and some other platforms.”

    Comment from 1 Feb 2026 in “The history of C# and TypeScript with Anders Hejlsberg | GitHub”

    “C# since getting Native AOT and the low level programming improvements, is close enough to Modula-3 design”

    Comment from 30 May 2026 in “Zig: Build System Reworked”

    “C# Native AOT gets rid of the JIT and gives you a pretty good perf+memory profile compared to the past.”

    Comment from 22 Dec 2025 in “Rue: Higher level than Rust, lower level than Go”

What people warn about

Each mark is one comment

  • Too many bolted-on features

    “Too many -- WAY too many -- "features" from Javascript and functional languages have been jammed into C#, and the language has suffered for it.”

    Comment from 12 Nov 2025 in “.NET 10”

    “It's mostly a bunch of shiny-looking language features being bolted on, all in ways that make the language massively more complex.”

    Comment from 8 Apr 2026 in “Explore union types in C# 15”

    “while both are decent languages, C# is the one that likes implementing every conceivable language feature immediately”

    Comment from 12 Nov 2025 in “.NET 10”
  • Large AOT binaries, limitations

    “there are a lot of limitations if you want AOT compilation and you still get the bloated binary and limited performance”

    Comment from 19 Aug 2026 in “Mojo is now open source!”

    “The self-contained binaries still have pretty poor startup time and are large since they contain the whole JIT.”

    Comment from 17 Jul 2026 in “G# – A modern .NET language with Go, Kotlin, and Swift ergonomics”
  • Awkward for allocation-free code

    “Writing C# that doesn't allocate is like wearing a straightjacket and the language doesn't help you much with manual memory management.”

    Comment from 13 Feb 2026 in “D Programming Language”

    “C# is too much of a you hold it wrong language, you can easily avoid the problem you describe, but it is such a pain”

    Comment from 24 May 2026 in “Improving C# Memory Safety”
  • Weaker outside Windows

    “Yes it can be done and it's helpful for cross platform with windows but I wouldn't consider it a first class citizen.”

    Comment from 1 Feb 2026 in “Swift is a more convenient Rust”

    “C# has close to zero community and only really works properly in Windows which is far past its glory days”

    Comment from 12 Apr 2026 in “High-Level Rust: Getting 80% of the Benefits with 20% of the Pain”

“less verbose Java with async/await like you have in other languages, and better performance than Typescript”

RecommendsComment from 28 Oct 2026 in “Python's experimental JIT to be removed”

“IMO better syntax and VM than Java and easier to write performant code than other VM based langs like Python”

RecommendsComment from 23 Oct 2026 in “Hedra is a 3D open world game I wrote from scratch while in highschool”

“Its async model is a pain point, but otherwise it really does a great job of being able to accommodate a vast range of use cases”
