F# Online

YouTube video by Scott Hanselman What is .NET? What's C# and F#? What's the .NET Ecosystem? .NET Core Explained, what can .NET build?

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).

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.

GitHub - fsprojects/FSharp.MongoDB: Add support for F# types to .net MongoDB.Driver Add support for F# types to .net MongoDB.Driver. Contribute to fsprojects/FSharp.MongoDB development by creating an account on GitHub.

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

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)

An ode to "slowly" handcrafted code

When I open my social media feeds, it's obvious: the age of writing code with our fingers is ending. LLMs can write code much faster.

But was it ever about the speed of code creation? I think not.

A great interview.

And as an F# developer, I see many parallels.

And I will stick with F# - fits our needs better regarding application development.

Dimensional Type Safety Across Execution Models From Ada to Dataflow: How Intrinsic Units of Measure Puts F# in a New Orbit

We've written about #fsharp CEs, Active Patterns and Quotations getting first-class treatment in 'fsnative' - our fork of the fsharp compiler. But units of measure gets its own entry as it's critical to so many of our broader ambitions for the platform. speakez.tech/blog/dimensi...

I decided to clean it up a bit (not good enough I know) and add a small skybox with some starry night in the background
My little QA told me that there's a lot of glitches I need to fix though 😆
