Expert F# 3.0

Expert F# 3.0 is about practical programming in a beautiful language that puts the power and elegance of data-rich functional programming into the hands of professional developers. In combination with .NET, F# achieves unrivaled levels of programmer productivity and program clarity. Expert F# 3.0 is: A comprehensive guide to F# by the inventor of F# A treasury of F# techniques for practical problem-solving An in-depth case book of how F# applications and of F# 3.0 concepts, syntax, and features F# isn't just another functional programming language. It's a general-purpose language ideal for solving real-world development problems. F# seamlessly integrates functional, imperative, object-oriented and query programming styles so you can flexibly and elegantly solve any programming problem. F# 3.0 combines this with the seamless data-integration capabilities of F# Information-Rich Programming. Whatever your background, you'll find that F# is easy to learn, fun to use, and extraordinarily powerful. F# will change the way you think about--and go about--programming. Written by F#'s inventor and two major F# community members, Expert F# 3.0 is a comprehensive and in-depth guide to the language and its use. Designed to help others become experts, the book quickly yet carefully describes the paradigms supported by F# language, and then shows how to use F# elegantly for a practical web, data, parallel and analytical programming tasks. The world's experts in F# show you how to program in F# the way they do!
