F# brings the power of functional-first programming to the .NET Framework, a platform for developing software in the Microsoft Windows ecosystem. If you're a traditional .NET developer used to C# and Visual Basic, discovering F# will be a revelation that will change how you code, and how you think about coding.

In The Book of F#, Microsoft MVP Dave Fancher shares his expertise and teaches you how to wield the power of F# to write succinct, reliable, and predictable code. As you learn to take advantage of features like default immutability, pipelining, type inference, and pattern matching, you'll be amazed at how efficient and elegant your code can be.

You'll also learn how to:

Exploit F#'s functional nature using currying, partial application, and delegation
Streamline type creation and safety with record types and discriminated unions
Use collection types and modules to handle data sets more effectively
Use pattern matching to decompose complex types and branch your code within a single expression
Make your software more responsive with parallel programming and asynchronous workflows
Harness object orientation to develop rich frameworks and interact with code written in other .NET languages
Use query expressions and type providers to access and manipulate data sets from disparate sources

Break free of that old school of programming. The Book of F# will show you how to unleash the expressiveness of F# to create smarter, leaner code.

Clear, concise, well organized

As I write this review (March 2021) this book is six years old and it covers F# 3.1 while F# 5.0 is the current version. Picking up this book would, by some, be considered historical research. Still, even though I have newer books on F#, this is this book that I reach for for my day to day programming chores. It seems that 99% of what I need to know was in 3.1 and this book is much better at clearly describing things than the more recent books. Even the typography is better (why do recent books choose such a large font and layout code with so much spacing and wrapping that it is hard to read?). And at a svelte 282 pages it is a delightful example of "K&R" concision in a world of computer books that are priced by the pound (as in weight). I strongly encourage the author to produce a Second Edition if for no other reason than to get this book in front of more eyes when everyone using Amazon is sorting by Publication Date.

Good book for starting with F#

Reviewed in the United States on January 12, 2016

Good introduction to F# and gets you quickly started (with Visual Studio). Covers lots of concepts. However, it does leave you with some unanswered questions here and there. All in all a nice read for beginners.

Okay. Not quite a reference, not quite an instructional book. A "tweener".

Reviewed in the United States on October 24, 2014

Verified Purchase

Disappointed... I found that this book wasn't in depth enough to be a reference but too short on whys and hows to be an instructional book. I suppose that if you've already read an F# reference or two and wanted to reinforce your knowledge then this book would be a good fit. For me, I was hoping for something that would help me "think functionally" and it didn't do that for me since it was more about language features than how best to use those features. That said it didn't explain the language features as clearly and precisely as I would have liked. Maybe this is just a case of unrealistic expectations on my part based on prior reviews.

A great reference book for F# beginners coming from another language.

Reviewed in the United States on March 31, 2014

This book provides a clean and concise intro to F# for beginners covering almost every aspect of the language. I think it might actually be the first to have reasonably in-depth coverage of quotations. The only downside to this book is that it doesn't have any assignments for the user to do as they learn (the vast majority don't). Overall, a well worthwhile read for the experienced C# developer looking to learn F#.

This is a great introduction to F# and by extension functional programming. The primary downside of the book is that like many coding texts, it’s fairly dry.

This book has everything we need to learn in F#, but in a confusing order. The examples just pop up with a feature that will be explained later in 3 pages..I have attempted to read my copy multiple times..but didnt succceed even once. I do look it up for some reference, and i get answers..but if i have to learn F# from this book... I will not be a ahppy person.

Good Overview of F#'s Features

Reviewed in Germany on March 25, 2020

Verified Purchase

The book delivers a very good starting-point for learning F#. But there is one major drawback for the kindle-edition: all code-examples are rendered without line-breaks (for whatever reason).
This is very annoying, especially with F#'s line-based syntax. Unexperienced programmers may have a hard time figuring out the correct syntax of the examples. Let's just hope that this will be fixed some time...

Summary: this is not a bad book, just not "the one", at least for me. I will refer to it in the future, but as indicated at the bottom I found better resources to teach the language.

F# is my favorite functional language, since at least for me reading/writing it - is as close I have at this point to thinking the algorithm. That said, I read somewhere that F# has 97 keywords (compared e.g. to Scala's 40'ish). Meaning that mastering this language requires to go through quite a lot. Unfortunately this book was not the one book I will turn to for that task.
It did nice job with a lot of chapters but also horrible job with others - such as the Object Oriented one. With so much to cover in this language, I think that listing everything is just not the right approach for someone who wants to get her/his head around the language. I like a top to bottom approach. Understanding the high level and then drilling. I could not get that sense through the book.
Moreover, I personally did not like much the notion of forward reference. The writer describes a lot of examples which you will get only later in the book/chapter. I find this confusing and discouraging when learning a new language. Luckily this was not my first book, but still it felt odd when I had to get a page or two, not grasping the examples.
My recommendation to anyone is to follow two online sources ... which in combination seem like the best way to learn the language:
Primarily the online wikibook for F# - which I highly recommend! ...[...]
As a side reference the MSDN F# language reference ...[...]
