It combines the succinctness, expressivity, efficiency, and compositionality of typed functional programming with the runtime support, libraries, interoperability, tools, and object models of modern programming frameworks. The aim of this book is to help you become an expert in using F# for a range of practical programming problems. Functional programming has long inspired researchers, students, and programmers alike with its simplicity and expressive power. Applied functional programming is booming: a new generation of typed functional languages is reaching maturity; some functional language constructs have been integrated into languages such as C#, Python, and Visual Basic; and there is now a widespread expertise available in the pragmatic application of functional programming techniques. There is also strong evidence that functional programming offers significant productivity gains in important application areas such as data access, financial modeling, statistical analysis, machine learning, software verification, and bio- informatics. More recently, functional programming is part of the rise of declarative programming models, especially in the data query, concurrent, reactive, and parallel programming domains. F# is a “functional-first” language, where functional programming is the first option used for solving most programming problems. However, F# differs from many functional languages in that it embraces imperative and object-oriented (OO) programming where necessary. It also provides a missing link between compiled and dynamic languages, allowing the idioms and programming styles typical of dynamic languages while preserving the performance and robustness of a strongly-typed compiled language. The F# designers have adopted a design philosophy that allows you to take the best and most productive aspects of these paradigms and combine them while still placing primary emphasis on simple functional programming techniques. This book helps you understand the power that F# offers through this combination. F# offers an approach to computing that will continue to surprise and delight, and mastering functional programming techniques will help you become a better programmer regardless of the language you use.

Or perhaps settled an argument concerning distances with “the length of my arm is about 20 inches, and that’s about two arm-lengths…?” You might not be willing to fall for such obviously flawed short-cuts, but as your humble author I will admit that I have. There is elegance to using the right tool for the job. And, just like a hammer or a tape measure, programming languages are tools like any other. Throughout this book you will discover that while F# isn’t the best tool for every situation, it is the perfect tool for some situations. This book is about showing you how to use the F# programming language as a general- purpose tool, with an emphasis on the specific domains where it can lead to dramatic boots in productivity. Along the way you will pick up a knack for functional programming; a semi-mysterious collections of concepts that can help you rethink your programs regardless of the host programming language. Introducing F# So what actually is F#? In a nutshell, F# is a multi-paradigm programming language built on .NET, meaning that it supports several different styles of programming natively. I’ll spare you the history of the language and instead just go over the big bullets: • F# supports imperative programming. In F# you can modify the contents of memory, read and write files, send data over the network, and so on. • F# supports object-oriented programming. In F# you can abstract code into classes and objects enabling you to simplify your code. • F# supports functional programming, which is a style of programming which emphasizes what a program should do, not explicitly how the program should work. • F# is statically typed. Being statically typed means that type information is known at compile time, leading to type-safe code. F# won’t allow you to put a square peg into a round hole. • F# is a .NET language. It runs on the Common Language Infrastructure (CLI) and so it gets things like garbage collection (memory management) and powerful class 1 www.it-ebooks.info O’Reilly Media, Inc. 4/2/2012 libraries for free. F# also supports all .NET concepts natively, such as delegates, enumerations, structures, P/Invoke, and so on. Even without all the jargon, it is clear that F# is powerful language. But don’t worry; we’ll cover it all step by step. Who This Book Is For This book isn’t intended to be an introductory text on programming and assumes familiarity with basic concepts like looping, functions, and recursion. However, no previous experience with functional programming or .NET is required. If you come from a C# or VB.NET background then you should feel right at home. While F# approaches programming from a different viewpoint, you can apply all of your existing .NET know-how to programming in F#. If you come from an OCaml or Haskell background then the syntax of F# should look very familiar. F# has most of the features of those languages, and adds many more to integrate well with .NET. What You Need to Get Going F# is “in the box” of Visual Studio 11. This includes the F# compiler and project system, and contains all the features such as syntax highlighting and IntelliSense that you would expect. Outside of Visual Studio and on non-Microsoft platforms, you can still write and deploy F# applications using the open source Mono platform (http://www.mono- project.com/). If you are running F# on Windows, then the first chapter of this book will show you how to get set up using Visual Studio. Otherwise, Appendix A will walk you through getting F# set up on non-Microsoft platforms.
