    You can get C# to run without the stdlib, and use it as a native language with some effort. Here's an example running Hello World as a C# EFI boot program:

    Background: I touched C# a little over 5 years ago writing ASP.NET MVC + jQuery apps and decided I hated it then.

    About 6 months ago I had a side project where I took a C++ library and decided I'd try to translate it into every language that supports C/C++ Interop, to have a canonical "C Interop reference + comparison" repo for anyone interested

    I found out that C# could do this, and started looking into how.

    Long story short, it's now possible to use C# and .NET to directly interop with C/C++. Function Pointers, structs and all. You can publish a binary or static/dynamic library for any platform that's natively compiled -- zero dependencies.

    It allows you to manually allocate memory and provide allocation strategies. Shit, you can even turn the GC off entirely (at this point the language is very barebones).

    See ZeroSharp by same author:

    So on top of this surprising viability for fairly low-level or native programming, it's also:

    - Just generally good at everything/bad at nothing

    - Blazingly performant, and getting faster consistently. Both at a language/computation level, and for things like web servers. ASP .NET Core Kestrel webserver has throughput only topped by a handful of Rust/C++ libs, and most recent preview included a new functional router API that increased throughout by +100,000rps.

    - C# as a language is evolving rapidly and has already become a solid multi paradigm lang. Adopting features like pattern matching and lambdas. It has LINQ. It's actually pleasant to write now and doesn't always feel like verbose enterprise garbage.

    - The tooling and ecosystem and C# and .NET are rivaled only by the JVM

    There's more but that's off the top of my head.

    Needless to say the last few months visiting C# and .NET land have changed my former opinion.

    The author’s ZeroSharp project is also interesting. It shows how you can compile C# without any runtime. No garbage collection, no exceptions. You can perform stunts like make a 5KB Hello World or a EFI application that runs with no operating system:

    I did a survey recently of binary sizes for .NET apps and comparisons to other languages. Things like NativeAOT (on which Bflat is built) and Graal Native Image let these languages get down to a binary size , startup speed, and deployment model similar that enjoyed by Go and Rust developers.

    Since C# is inherently a managed environment, it has to interface somehow with the drivers and/or kernel somehow, so the notion of a pure C# engine is not something you should probably pursue. There are incredible feats of coding black magic (such as zeroSharp) but that is a whole different kind of story.
