My main project over the last few years has been a photobooth, so I've done server-side in suave (I LOVE suave compared to any other .net framework), client-side in WPF (F# experience in WPF is meh), and a bundle of other mini projects. I did it in F# because it was interesting, not because it was more productive at the time. My personal landing point is about #6 in the turtles article. I still like classes and inter…

Why is this needed in F#? Something to do with immutability?

I created a gist of the pattern I've found to be most successful when doing an app in F#.

This assumes you want to use records for your data: records don't have inheritance. So whereas in C# you could create a UserDb that extends User with the Id/DateAdded fields, in F# that's not idiomatic.

I am sure there could be a good way to automate this using type providers, but I haven't tried it yet.

Everything in Windows has keyboard shortcuts, not so on Linux and MacOS (e.g. you can't open a random menu item with the keyboard).

Um yes you can? I mean i do this all the time like many times a day all the time... Alt key is your friend here

Not on MacOS.

MacOS is as unusable as Windows to me.

I think it depends on what you are used to though.
