What is #dotnet btw? What is C# and what is F# ? youtu.be/bEfBfBQq7EE?...
Trend is to generate a compiler using LLM... So here is my contribution: FScript, an embeddable #fsharp lang inspired interpreter. Entirely developed with Codex, no shame 😃
Execution is sandboxed and extensible, also support structural record annotation (think Typescript).

F# Weekly #6, 2026 - FScript & An ode to “Slowly” handcrafted code #fsharp sergeytihon.com/2026/02/07/f...
⚡️ Mibo and WREN stack push F# into new terrain
🏷️ #devdigest #dotnet #net #fp #fsharp
https://devdigest.today/goto/5254
Src: latest Fireship 🔥 vid on .NET, this is why you can mix and match #csharp and #fsharp code in the same solution, referencing one from the other with full intellisense and cross language debug support in Vs,VsCode,Rider ! Try F# in 2026 for smt fun like a small library and call it from C# ☺️✨
⚡️ F# emerges as the most token-efficient static language
🏷️ #devdigest #dotnet #net #fp #fsharp
https://devdigest.today/goto/5270
I told claude code to NEVER EVER touch my #fsharp code base files, i.e. anything *.fs, but instead do all implementations in script files, so I can first check what is going on. And I am so glad I did this.
It's been a while I shall have completed FSharp.MongoDB - but literally had no time to spend on fixing a stack overflow.
Now it is feature complete and fully supports NRT 🎉
Enjoy F# + MongoDB ! #fsharp #mongodb

🚀 #NBomber v6.2.0 is out!!!
The team has focused on improving HTML reporting and cluster usability, as well as adding powerful observability support.

⚡️ F# community gears up for 2026 (un)conference

Definitely. Would people be interested in coming to Bergen, Norway? We could combine combine with hiking trips up the mountains.
I wonder... would there be any interest in some F# event / (un)conference in 2026?
I always wanted to do something similar to F# Creators Workshop (which @dsyme.bsky.social organised years ago in Cambridge) or Elm Camp (which has been for last couple of years)
#fsharp
I did a new thing with #fsharp on backend and pinch🤏 of #typescript on frontend. It's called Triple19, running on www.triple19.com and it's all about my new-ish hobby - Darts. It's quite complex and I'll do tech talk about it one day, but now if you would give it a shot, would ya? #darts
SqlHydra - v3.4 is out today. It is a rollup of the last two releases. Lots of nice, new features and some deprecated ones to help transition into an upcoming v4.0. #fsharp
github.com/JordanMarr/S...
Fidelity framework and the Firefly compiler will move #fsharp to S-tier (by those measures)
⚡️❄️This is such a great showcase for #fsharp! 🔌
