Or C# with ASP.NET Core which is much closer to rust in performance.

> Or C# with ASP.NET Core which is much closer to rust in performance. I haven't noticed that C# is faster than Go, or that it's as fast as Rust/C++. Except in selected micro-benchmarks, of course. C# is at best in the same bracket as Go: https://www.techempower.com/benchmarks/#section=data-r19&hw=ph&test=query https://www.techempower.com/benchmarks/#section=data-r19&hw=...

    The fastest .Net based library scores a 58%, while a framework based on Go scores 52%. The weights are arbitrary, so can't infer a lot from the 6% delta between .Net and Go - except that they compare favorably with each other in terms of performance.

      The fastest .NET library is ASP.NET Core, which is a standard, mature, off the shelf framework. Compared to the golang version using fasthttp, which is non-standard and makes compromises to achieve speed, and I'd avoid it for production.

  In my experience ASP.NET and its frameworks are potentially much slower than raw C#. As much as C# is supposed to be a fast language, whenever I run into a C# web app it seems to be inexplicably slow.

    I'm not sure why anyone would be downvoting your data point. I am pretty bothered at how much emphasis folks throw behind the TechEmpower benchmarks. If you really dig into the implementations for the top languages, it's easy to see how far from the real world, those apps are. In the case of C#/ASP.NET, as soon as you add EntityFramework (or Dapper, if that's your thing) and some real-world querying of a database. You're looking at a pretty big slow-down. I'm certain things can be done to speed it up though.

Is that free in any way?

  It's free in all the ways

  C# or ASP.NET Core never costed anything. The cost is in certain versions of Visual Studio, but that is not required. Besides Visual Studio, Visual Studio Code is popular too.

    I can recommend Jetbrains Rider [1] for anything C#. I prefer it over Visual Studio even. [1]: https://www.jetbrains.com/rider/ https://www.jetbrains.com/rider/

    Is it also free to deploy? Can you deploy it on Linux?

      Yes. It is also fairly straightforward to dockerize dotnet core apps[0]. [0] https://docs.docker.com/engine/examples/dotnetcore/ https://docs.docker.com/engine/examples/dotnetcore/

  The C# compiler roslyn, the dotnet runtime (Jit compiler, ...), and ASP NET Core are all MIT or Apache licensed and run officially supported on mac os, linux and windows.
