| Overview
Expert F# is about practical programming in a beautiful language that puts the power and elegance of functional programming into the hands of .NET developers. In combination with .NET, F# achieves unrivaled levels of programmer productivity and program clarity. This books serves as
The authoritative guide to F# by the designer of F# A comprehensive reference of F# concepts, syntax, and features A treasury of expert F# techniques for practical, real-world programming
While inspired by OCaml, F# isn't just another functional programming language. Drawing on many of the strengths of both OCaml and .NET, it's a general-purpose language ideal for real-world development. F# integrates functional, imperative, and object-oriented programming styles so you can flexibly and elegantly solve programming problems, and brings .NET development alive with interactive execution. Whatever your background, you'll find that F# is easy to learn, fun to use, and extraordinarily powerful. F# will help change the way you think about and go about programming.
Written by F#'s designer and two active contributors, Expert F# is the authoritative, comprehensive, and in-depth guide to the language and its use. Designed to help others become experts, the book gives a thorough introduction to the F# language from quick essentials to in-depth advanced topics such as active pattern matching, aggregate data types and operators, sequence expressions, lazy values, mutable data and side-effects, generics, type augmentations, functional decomposition and code organization.
The second half of the book is devoted to examining the practical application of F#, providing elegant solutions to common programming tasks including UI implementation, data access, web and distributed programming, symbolic and numerical computations, concurrent programming, testing, profiling, and interoperability with other languages. The latest hot developments in F# and .NET are also addressed, including Active Patterns, implicit class construction, integration with LINQ over relational data, meta programming and useful tips for working with Visual Studio and F# command-line tools.
The worlds foremost experts in F# show you how to program in F# the way they do!

Reader Reviews From Amazon (Ranked by 'Helpfulness') Average Customer Rating: based on 17 reviews. Assumes Experience with Functional Programming, 2009-06-13 Reviewer rating: This book states in the beginning that you don't have to know functional programming in order to understand the material. I would argue that this is not true.
I've taken a course in functional programming and so not much was new to me. Having read some of the other reviews, I realised that the book is not very friendly to people who are professional programmers with no past experience of functional programming (though you could argue that one cannot be a professional programmer without such experience!).
That said, this book covers so many different topics in addition to the core concepts of the language. This shows you, time and time again, how you can use F#. It gives you plenty of ideas. So, this book is really good, no doubt about that. | Study OCaml First!!, 2009-06-11 Reviewer rating: F# is basically OCaml for .net. This book covers details of F# for .net. However I felt confused about some syntax of F# which this book does not explain clearly. After looked up tutorials for OCaml on the internet, I found there are materials which can help you to better understand fundamentals of OCaml(F#). If you are new to F#, make sure you go through several OCaml tutorials first before you start exploring this book. | A solid reference, and a pleasure to read, 2009-05-31 Reviewer rating: Reviewer's background - some academic work in functional programming (Lisp), and 23 years as a developer in the aerospace business (Ada, C++, etc).
Of all the computing books I've purchased over the years, I would rate this as one of the finest. It has that very rare combination of: working as reference for a language; exposing most of the "real world" uses of it; and also being a pleasure to read. I call it a pleasure, not because it has any great humour or anecdotes, but because the authors' style exposes the beauty of the subject in a way that appeals to programmers who love their craft.
As others have said, the structure of the book works very well. The first half explains all the language constructs, and the second shows the how to use the language in the .Net world - web apps, databases, etc.
What I like most about the style is that it is both succinct, and readable. One can sense the authors working to keep the book down to 600 pages, while providing the essential reference details, and sharing their most important insights into F# and software in general. They achieve this mostly through the carefully arranged examples, and informal "tips". Whenever I look at an example for a particular purpose (eg. a database interface) I see F# constructs being used that also demonstrate something else about the language - to explain all these points would make the book unmaneagable, so it's up to the reader to observe and learn as they read.
The two negative reviews of this book do make a valid point - that this book isn't good for learning functional programming. Its scope is too large to concentrate on the actual skill of writing functional programs (apart from the expert tips). If I could improve it in one way, I would have a set of sample problems at the end of each chapter, with the solutions available online.
The book also has an optional e-book for $10. I strongly recommend it. I use both the hard copy, and the e-book (but mostly the e-book).
| (for F# Expert) F#, 2009-05-31 Reviewer rating: Early examples that simply do not work. Some have leave out necessary #r or 'open' statements. How do you expect the reader to proceed in this book without having a foundation of the simple parts of the language? Excerpt: [expr :: expr "Cons" an element with a list 1 :: [2; 3]
okay, try that, does not work...and wtf does "cons" mean, referenced many times in the following paragraph. But @ works.
Maybe the writers should have warned the reader "for demonstrational purposes only, do not try" or "read the documentation first".
Again is introducing '|' with the examples in the section that introduces basic list operators, without bothering to explain how '|' works. It could be a trivial operator, but the reason a reader spends on a book and not go straight to the documentation is because the book is expected to guide the reader's learning.
BTW, the "Who this book is for" section reads "We assume you have some programming knowledge and experience." Yes, C#, not F# which is why I was reading this book.
Somehow expected different from the main designer of F#, 2 co-authors, and 1 technical reviewer. | Good book, but beware tiny fonts in Kindle version, 2009-04-02 Reviewer rating: This is a good introduction to F#. I would rate it at 4 stars for its content, but I wish I had known, however, that the kindle version of the book does not scale the font size at all for the many code samples included. Even worse, the font used for the samples is tiny. I have to hold the kindle about 6 inches from my face in order to read the samples. Note that the trial chapter that you can download does not show the problem, it only happens in later chapters. |
