From the Foreword: You will never look at your code in the same way again.

about the technology

Functional programming languages are good at expressing complex ideas in a succinct, declarative way. Functional concepts such as "immutability" and "function values" make it easier to reason about code—as well as helping with concurrency. The new F# language, LINQ, certain new features of C#, and numerous .NET libraries now bring the power of functional programming to .NET coders.

about the book

This book teaches the ideas and techniques of functional programming applied to real-world problems. You'll see how the functional way of thinking changes the game for .NET developers. Then, you'll tackle common issues using a functional approach. The book will also teach you the basics of the F# language and extend your C# skills into the functional domain. No prior experience with functional programming or F# is required.

what's inside
