Some bittersweet news: in about a month I will be moving to the new team inside of Microsoft – Microsoft C++ compiler backend as lead.I will still be spending about 20% of my time contributing to F# compiler (roughly same amount as now), just not as part of the team.

Advent of Code

Two years ago, we decided to spice up the Advent season by creating a private board for those participating in Advent of Code (AoC) and coding in F#. If you’re planning to dive into AoC this December, we’d love for you to join us. Let’s make this holiday season one to remember!

Reminder for every who solves adventofcode.com in #fsharp It also starts tomorrow, and we have a private board with F# folks 393584-7799c026. You are welcome to join!

I was bored so I forked @gleamlang and added .NET compilation support via #fsharp.

It's very rudimentary but it's functional 🙃 I'll probably write up a blog post or something about it at some point but for now I just wanted to share what I've got:https://t.co/vrUj5Esrhp

Finally with FAKE 6.1.3 you can build .NET 8 projects, so you can update old fake-cli projects without major refactoring. Like PR here to update @FSharpLint to support .NET 8: https://t.co/M8VBFqiCdw #fsharp #dotnet
