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 generalpurpose language ideal for realworld development. F# integrates functional, imperative, and objectoriented 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 indepth 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 indepth advanced topics such as active pattern matching, aggregate data types and operators, sequence expressions, lazy values, mutable data and sideeffects, 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 includinguser interfaceimplementation, 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# commandline tools.

The worlds foremost experts in F# show you how to program in F# the way they do What you'll learn How to use F# for functional, imperative, and objectoriented programming How to code elegant F# solutions with expert technique and style How to develop Windows, web, graphics, and database applications in F# How to do numerical, concurrent, lexical, and symbolic processing in F# How to interoperate with C and COM Who this book is for

This book is for anyone interested in state-of-the art .NET programming. Professional programmers will find it engrossing. F# provides invaluable insight into the future of both C# and VB, which are now adopting some (but far from all) of the functional features of F#. Once they learn F#, few feel like returning to either C# or VB. The academic community will find F# the answer to a decades-long prayer: a language suitable for teaching computer science that also excites and empowers students because it can be used not just in the classroom, but also in the real world.
