Top 23 C# Compiler Projects

  • Roslyn

    The Roslyn .NET compiler provides C# and Visual Basic languages with rich code analysis APIs.

  • Project mention: Generating C# code programmatically | dev.to | 2024-04-05

    Recently, while creating some experimental C# source code generators (xafero/csharp-generators), I was just concatenating strings together. Like you do, you know, if things have to go very quickly. If you have a simple use case, use a formatted multi-line string or some template library like scriban. But I searched for a way to generate more and more complicated logic easily - like for example, adding raw SQL handler methods to my pre-generated DBSet-like classes for my ADO.NET experiment. You could now say: Use Roslyn and that's really fine if you look everything up in a website like SharpLab, which shows immediately the syntax tree of our C# code.

  • ClojureCLR

    A port of Clojure to the CLR, part of the Clojure project

  • Project mention: Dada, an Experiement by the Creators of Rust | news.ycombinator.com | 2024-03-06

    Yea, that's true. I forgot about that. I did think of Clojure CLR, but I don't get the impression that this is an all that natural or used implementation. ClojureScript is obviously much more used, although it is still a "different" language.

  • DistIL

  • Project mention: Classes vs. Structs in .NET. How not to teach about performance | news.ycombinator.com | 2023-11-04

    How is that relevant to the vast majority of the code targeted by LINQ?

    The niche scenario you have outlined is partially covered by a recent System.Numerics.Tensors package update (even though I believe it would have been best if there was a community-maintained package with comparable quality that can be decoupled from .NET release cycle and trade-off support/compat guarantees in favour of more aggressive improvements in the future).

    The goal of LINQ itself is to offer optimal codepaths when it can within the constraints of the current design (naturally, you could improve it significantly if not for backwards compatibility with the previous 15 or so years of .NET codebases). The argument that it's not good because it's not the tool to do BLAS is just nonsensical.

    There is, however, an IL optimizer that can further vectorize certain common patterns and rewrite LINQ calls into open-coded loops: https://github.com/dubiousconst282/DistIL
