About this book


Why just get by in F# when you can program in style! This book goes beyond syntax and into design. It provides F# developers with best practices, guidance, and advice to write beautiful, maintainable, and correct code.

Stylish F# covers every design decision that a developer makes in constructing F# programs, helping you make the most educated and valuable design choices at every stage of code development. You will learn about the design of types and function signatures, the benefits of immutability, and the uses of partial function application. You will understand best practices for writing APIs to be used by F#, C#, and other languages. Each carefully vetted design choice is supported with compelling examples, illustrations, and rationales.

What You'll Learn:

  • Know why, when, and how to code in immutable style
  • Use collection functions, piping, and function composition to build working software quickly
  • Be aware of the techniques available to bring error handling into the mainstream of program logic
  • Optimize F# code for maximum performance
  • Identify and implement opportunities to use function injection to improve program design
  • Appreciate the methods available to handle unknown data values
  • Understand asynchronous and parallel programming in F#, and how it differs from C# asynchronous programming

This book is for any developer who writes F# code, and wants to write it better.
