.NET 11 Preview 2 is now available! The second preview of the upcoming .NET version, .NET 11, is available as of March 10th, 2026. The official announcement blog is available, and it gives you some of the most striking changes as of Preview 2. Read the official announcement The following changes to the preview were made since the last preview: Generic GetTypeInfo for System.Text.Json: The GetTypeInfo() and TryGetTypeInfo() methods have earned their own generic variants, which allows you to return a strongly-typed metadata directly without having to go through a process of casting to the appropriate type.

Lazy Evaluation of Sequence in F# I’ve been coming back to something I read in “F# in Action” about sequences and how they’re lazily evaluated. Lazy evaluation is not someth...

Case in point: I had never encountered the concept of "lazy evaluation" before (or at least don't recall it if I did). But I wrote a bit about how this applies to #fsharp sequences and how to take advantage of it.

The more I learn about functional programming in general, and #fsharp in particular, the more I feel like I'm starting my programming journey "Ab initio".

Looking back at your posts, I see you've been sharing so many interesting thoughts! You've been really diving into games like "Marathon" and reflecting on technology and programming languages like #fsharp. It's so cool to see your passion and how you connect different ideas! You're

Been doing @gleam.run and #fsharp side by side the past few days (porting libs).

Two of the best programming languages I have worked with. And so much you can enrich your knowledge of one with the help of the other.

I think I get List.collect
let myList = [ 1 .. 3 ]

// return list of n and n * 2
myList
|> List.collect (fun n -> [ n; n * 2 ])
int list = [1; 2; 2; 4; 3; 6]

// return list of tuples of n and n * 2
myList
|> List.collect (fun n -> [ n, n * 2 ])
(int * int) list = [(1, 2); (2, 4); (3, 6)]

MOTHER, Metaprogramming, and the Meta Language I've written about MOTHER's philosophy and its mechanics. This post is about what I realized after I had some time to step back and reflect on the system once it was in place. MOTHER is a metaprogram...

Yesterday I went down a rabbit hole of personal reflection (no pun intended) of meta programming and how the approach to an agentic system I took with MOTHER, written in #fsharp, actually aligns nicely with F#’s lineage in the programming language world.

Great article and thanks for posting! As someone still new to functional programming and #fsharp, I really appreciate the examples you provided and the comparisons to the imperative way of doing things.

Stupid question: What's the difference between exceptions and results?

Why I Hope I Get to Write a Lot of F# in 2026 The FP language that does what Elm does, but on the backend, with full .NET support

Just my personal observation as a complete #fsharp newbie but when it comes to getting LLM assistance to troubleshoot code, ask questions or get clarification on things:

Trying to better understand the differences between using records types

type EmailAddress = { EmailAddress: string }

and single-case DU

type EmailAddress = EmailAddress of string

to provide type safety when wrapping strings in #fsharp 🤔

And I would love getting people on board using #fsharp to write great clinical decision software like #GenPRES. Great blog and I couldn't agree more with you. For complex domains (like medicine), #fsharp just shines!

I use the great AZD plugin to make working with Azure DevOps PRs simpler for JetBrains IDEs (plugins.jetbrains.com/plugin/22319... ). One of its many features is an AI-driven PR review. It gave me many good pointers, but it should sharpen its F# knowledge 😀

It’s awesome! ML type inference is great. try also #dotnet #fsharp it comes from ocaml and is part of dotnet-sdk, also has REPL and .fsx scripts, works well with nuget packages, if you interested . Benefits of dotnet/csharp but with a FP first Lang

Clef Language - WebView and Native Application Rendering
Clef Language - WebView and Native Application Rendering YouTube video by Houston Haynes

WebView and then Native GPU Control from Clef language - mind you it's loading one framebuffer but it's a start! This is actually a #cleflang and #fsharp story for now, but I'll be moving web generation to the Composer compiler soon. youtu.be/8egiPpVi4pg
