I’ve been teaching myself F# for a while now. I’ve read Programming F# by Chris Smith (great book) and I’ve written a few small scripts for getting the job done here and there.
But IMO the best way to learn a new programming language—and more importantly, the idioms that come with it—is to read a good open source codebase written in that language. Naturally, writing code in that language is crucial, but in the beginning, you’re basically struggling with your own ignorance about how things should be done. You could perform certain tasks one way or the other, but it takes experience to realize the flaws and virtues of each. Even after you’ve gotten a firm grasp of how things work, reading the code of people who have an even firmer one helps a great deal.
Most would agree that the most insightful parts of any learn-a-programming-language book are the code examples, and reading a well-written open source codebase is the next level of that.
So are there any out there for F#?
Ref this question.
IMO, F# PowerPack is the best code base there.
