    Can't speak to the others, but I'm pretty sure the F# team just doubled or tripled in size (it's still small though). Also the GitHub repo is very active: https://github.com/dotnet/fsharp .

  • Hot-reload in Fun.Blazor
    3 projects | dev.to | 27 Feb 2022
    I know csharp got hot-reload for blazor for a while, I also keep tracking on the fsharp issue and hope there is some miracle which can happen. But there is no progress here. So I decide to have a look for what I can do. To make dotnet watch work directly is too hard to me which required a lot of knowledge about FSharp.Compiler.Service and the IL format which csharp roslyn is using for patch the program for hot-reload.

  • What I wish I knew when learning F#

    You can simply contribute to https://github.com/dotnet/fsharp/, the maintainers are very friendly to new contributors in my experience (though the codebase is old and often quite hard to understand).
  • The Very First Post
    11 projects | dev.to | 10 Sep 2021
    The F# Programming Language: I consider F# as the functional-oriented sibling of C#. This language offers a nice introduction to statically-typed functional programming. It offers a really nice ML-like syntax, as well as some features like type providers (a way to define a schema for data such as a database table, JSON file, etc.).

What are some alternatives?

When comparing Fable and VisualFSharp you can also consider the following projects:

FunScript - F# to JavaScript compiler with JQuery etc. mappings through a TypeScript type provider

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

Bridge.NET - :spades: C# to JavaScript compiler. Write modern mobile and web apps in C#. Run anywhere with Bridge.NET.

F# - Please file issues or pull requests here: https://github.com/dotnet/fsharp

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

JSIL - CIL to Javascript Compiler

language-ext - C# functional language extensions - a base class library for functional programming

Nemerle - Nemerle language. Main repository.

ocaml - The core OCaml system: compilers, runtime system, base libraries
