That's what I'm working toward with my language-ext library [1]. Obviously more support for expression based programming would be welcome (and higher kinds), but you can do a lot with LINQ and a good integrated library surface.

Given few people anticipated ValueTuple and C# adding a more direct tuple syntax, I feel like it is only a matter of time before C# adds discriminated unions.

(There are multiple proposals tracking the idea. This seems the most comprehensive and "central": https://github.com/dotnet/csharplang/issues/7016)

  A native functional ASP.NET Core web framework for F# developers.

  

Giraffe is another interesting one to explore: https://giraffe.wiki/

Giraffe is nice because it is itself built "just" as ASP.NET Core Middleware so it plays a bit more nicely than Suave with a mixed stack of C#-defined Middleware.

It's more likely you accidentally fall back into just translating C# patterns to non-idiomatic F# with Giraffe, but it's also nicer when in that case of needing to live in both worlds and use a mixture of libraries built for C# ASP.NET projects.

• best-form

  The best form of documentation is the code itself

It isn't Haddock, it's simply inspired by Haddock. It's a library I wrote called best-form [1]. The README gives context:

"This is a C# doc-gen tool. It was primarily built to support my Language-Ext project. Which is non-idiomatic in its approach. I couldn't find documentation generators that did it justice. I also really liked the Hackage documentation style from Haskell, so have taken a styling approach from there (even if it looks a little dated now, it was always the documentation I felt most comfortable reading)."

language-ext isn't idiomatic C# and so idiomatic C# doc-gens have quite a bad time with this library. One of the major benefits over other doc-gens is it grabs the README.md from each folder and prepends it to any section, allowing me to write some contextual documentation outside of the auto-generated API documentation.
