SwaggerProvider v4.0.0 is live! 🎉 #fsharp Overhauled for speed, cleaner code gen, and better developer ergonomics. ⚡ Blazing fast zero-allocation hot paths 📅 Native DateOnly & TimeOnly support 📝 Richer IDE docs via inline XmlDoc ⚠️ Breaking: Legacy v2 compiler removed github.com/fsprojects/S...

11 years ago I’ve made first commit on the project that would later be known as Ionide. A lot has changed over all those years, but one thing remains - the biggest value of the project has been meeting awesome people from F# community, many of whom I’m proud to call friends. #fsharp

🚀 Serde.FS alpha.9 — Deterministic RPC for F# No reflection. No controllers. Just compile‑time RPC clients + routing. Includes: • [<RpcApi>] • ASP.NET RPC server • Deterministic JSON backend • Shared → Server → Client example github.com/serde-fs/Ser... #fsharp #rpc #aot #serde #dotnet

After a loooong vacation, I published a new version of #Feliz #DaisyUI library. Big kudos to Oleksiy Slyshyk, who did all the work (I just pushed the button 😁) #fsharp

RE#: how we built the world's fastest regex engine in F# iev.ee/blog/resharp... #regex #fsharp

The wait is over! Fable 5 Release Candidate is officially here. After a year of hard work from the community, we're bringing you: ✨ .NET 10 & F# 10 support 🐍 A massive Python update (now powered by a Rust core & PyPI!) 🌐 Cleaner JS/TS Pojo bindings fable.io/blog/2026/20... #fsharp #fablecompiler

Using GitHub Agentic Workflows "Repo Assist" automated repo assistant, I was able to 1. Clear all the lingering technical debt off the community library FSharp.Control.AsyncSeq today 2. Release a new version 4.0.0 with a major compat feature github.com/fsprojects/F... bsky.app/profile/did:...

F# folk - I'm having some success using GitHub Agentic Workflows to automate some backlog maintenance work in some older F# community repos. FSharp.Data: github.com/fsprojects/F... FSharp.Control.AsyncSeq: github.com/fsprojects/F... It's helping me re-engage with the repos and clean things up.

After some *checks notes* umm.. 6 years, I released a new version of my composable data visualization library, adding support for images! compostjs.github.io/compost/demo... I still think this is the best way of doing composable data visualizations. See the paper: www.cambridge.org/core/journal...

Adding a video streaming feature to my www.triple19.com application seems to be fun. The more features, the more stuff to talk about at some FP conference? 🤔

A new web page for my book! tomasp.net/cultures/ It has all the links you may need to get the open access PDF, buy a hardcopy or an ebook as well as some older talks & slides. If you run a podcast, conference or a user group, I'm always hapy to join & talk about something from the book!

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

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

F#+ 1.9.1 released ✨🥳 #fsharp www.nuget.org/packages/FSh... www.nuget.org/packages/FSh... See the release notes here: github.com/fsprojects/F... Many thanks to everyone that made this release possible! 😘

Looking forward to coming to this amazing conference exploring the gaps in computer science research!

A beautiful F# library for building AI agents on .NET: • Quotation-based tool discovery • Pipeline-style agent composition • Computation expressions for workflows • Railway-oriented error handling F# deserves a place in the agent era — and this is my contribution. #fsharp #dotnet

Here’s my post for Day 8: blog.bencope.land/f-in-product... #fsharp

Let me invite you to our last #dotnet Meetup this year. We have 3 great talks prepared for you, and of course food. 📍 Microsoft Office (Delta Building, Vyskočilova 1561/4a, Prague 4) 📅 Monday, December 8, 2025 🕗 5.30pm - 9.00pm English, Free entry www.meetup.com/microsoft-ev...

F# 10 enhances functional programming on #dotNET with nullable reference types, optimized equality checks, faster integral ranges, and improved tooling diagnostics. It reinforces F#’s reputation as a concise, reliable, and high-performance. Learn more: msft.it/63320tr2J2#dotNET

Fable 4 and Fable 5, both got a new release to make them work with .NET 10 🎉 #fsharp #fablecompiler

Great #dotnet #fsharp lang review youtu.be/CmML57XX2eg?... 🦔✨💕

Common terms in F# that I hadn't heard before coding with it: * Computation expressions * Railway-oriented programming * Partial application * Currying * Monads * Discriminated Unions * Exhaustive pattern matching Reason #7 F# Sucks - You start talking weird hamy.xyz/blog/2025-06... #fsharp

One thing that always surprises me is the .NET community's obsession with mappings and mapper libraries. I DO get the temptation to have a one-liner instead of 6 lines, but I genuinely believe that if this is a problem in your code, you either have too many layers or messed up your abstractions. 😁

okay this is extremely fucking funny

Adopting #daisyui is great! We've been using it with @dzoukr.cz 's SAFE(r) stack and love it. 💙 We're curious about Elmish.Bridge and websocket support. It hasn't gotten a lot of recent attention, but we're tantalized by the idea. 🍰 github.com/Nhowka/Elmis...

7 Reasons F# Sucks hamy.xyz/blog/2025-06... #fsharp

Computation Expressions aren’t just monads—they’re your DSL for async, validation, and more. Worth a revisit? Compositional IT can provide training courses to help you with your advanced F# skills - Let's have a chat. 🔍 #fsharp @fsharponline.bsky.social

Amaizing post

Have a potential #fsharp development job for full time hire. We are an #fsharp, DDD, CQRS, Event Sourcing team and looking to expand. We build Rockwell Automation's cloud backbone capabilities. Location has some flexibility and we are a hybrid team with part time remote (2 days a week).

JetBrains has been quietly building something special for the open-source LLM community. More details will be posted soon on Hugging Face. Stay tuned! 🧑‍💻

It's kinda amazing that Ionide is over 10 years old, eh... #fsharp

Don't miss the early registration deadline. Check out the technical papers, awesome keynotes and MoreVMs workshop talks & keynotes to see what you'd be missing!

I'm looking for somebody who would be willing to talk to me about Entity Framework Core and F# on a .NET Data & EF Core Community Standup (www.youtube.com/playlist?lis...). cc @dzoukr.cz #ef #efcore #fsharp

v3.0 release of SqlHydra today! #fsharp github.com/JordanMarr/S...

Mega kudos to @mangelmaxime.bsky.social for taking over the ownership of Feliz.Bulma.* packages on #nuget and #github I will keep contributing to Feliz.DaisyUI while he proceeds with Bulma. #fsharp #oss

I started playing with the new preview of #modelcontextprotocol support in #azurefunctions. It's a port of my existing Untappd MCP server and I'm very, _very_ early in the creation phase: github.com/jtucker/mcp-... Written in #fsharp fwiw

It's way more complicated than just that. * Covid did significant damage to all meetups - many did not restart, including F# meetups * Some people lost interest in fighting for F#, because some won (using it daily) * Yup, some people left, but some came (Amplifying F#) Always niche, but still cool!

A 11. série podcastu #PodVocasem je historií! Na závěr jsme si s Petr Polak pozvali nabušenýho Martina Šafránka, který nám vysvětlil, co je Data Vault a všechny věci s tím spojené. Dejte si poslední díl série a pomalu se těšte na další. ;) open.spotify.com/episode/4a0D...

Excited about building pretty UI's? Or do you prefer getting styling done as quickly as possible so you can move on to #backend work? Either way, DaisyUI got your back, by making writing a good-looking website a breeze! Shout out to @dzoukr.cz for maintaining Feliz.DaisyUI! #fsharp #UI #frontend

Creating good software is about creativity, good product design, understanding users needs… not about outputting thousands lines of code with single prompt

Soooo, AutoMapper, MediatR, MassTransit moving to commercial model at the same time. 😅 Really looking forward what impact it will have in the #dotnet world. 🤔 🔗 www.jimmybogard.com/automapper-a... 🔗 masstransit.io/introduction...

Even if 💯 appreciate the kudos, I need to emphasize that my template is just a "modification-for-MY-fit" and it's standing on the shoulders of giants from the original SAFE Stack (github.com/SAFE-Stack/S...). Without your work and contributions, all the modifications would be useless. Thank you! ❤️👏
