Folders in F# projects. How to do it? What to avoid?

I’ve been working on a new feature for Visual F# Power Tools extension, which would creating and maintaining folder structure within F# projects. I have to admit, it was not a pleasure to dig into VS SDK and try to get it working. The most annoying part: part of SDK related to Solution Explorer still uses COM interfaces… Second most annoying part: Solution Explorer complaining about completely correct project structure…

But anyway. The more I dig into it, the more weird behaviors I experienced. And because I don’t think I’m the only one struggling with folders in F# projects – there are couple questions on StackOverflow about this (like here and here) – and because there is also a known workaround how to force VS to show folders in your project – just manually edit .proj file – I decided to write about couple of problems you may run into trying to force F# project to contain folders.

Why contributing to an Open Source project is a good way to learn new language and/or technology

I’ve been trying to learn F# for quite a long time now, but there was never a good way to do it. First of all, I need some way to evaluate my work. It’s really easy to learn new language, but you never know if you’re using it right. That’s even more likely to happen when not only language is new but also general idea behind that language is much different. That’s the case with my F# learning. Almost every programming language I’ve used so far can be classified as object-oriented-first language. F# is different. It’s functional-first language and because of that it’s more about learning how functional programming looks like, not how F# syntax looks like. But I think I found a way to learn F# right. And the answer is: Open Source.

Learning F# and solving Digit Recognizer competition on kaggle

I’ve started learning F# couple weeks ago, but unfortunately after few days I got quite busy and after these days I still know almost exactly nothing about functional programming at all. That’s why I decided I have to look for some challenges and samples I could work on while learning. That’s how I found F# and Machine Learning Dojo slideshow and Digit Recognizer competition on kaggle. I decided to give it a try. Of course, the main goal is to learn F#, not to get 100% correctness in the competition. You should have it in mind while reading the post :)
