F# for C# Developers

Book Description

Extend your C# skills to F#—and create data-rich computational and parallel software components faster and more efficiently. Focusing on F# 3.0 and Microsoft Visual Studio 2012, you’ll learn how to exploit F# features to solve both computationally-complex problems as well as everyday programming tasks.

Topics include: C# and F# data structures; F# for functional, object-oriented, and imperative programming; design patterns; type providers; and portable support for Windows 8. You’ll examine real-world applications, including Windows 8-style HTML5 and JavaScript apps, along with cloud and service apps. You’ll write your own type provider. And you’ll see how to expand F# computation power to high-performance GPU computing.
