F# 4.0 Design Patterns

By: Gene Belitski

Overview of this book

Following design patterns is a well-known approach to writing better programs that captures and reuses high-level abstractions that are common in many applications. This book will encourage you to develop an idiomatic F# coding skillset by fully embracing the functional-first F# paradigm. It will also help you harness this powerful instrument to write succinct, bug-free, and cross-platform code. F# 4.0 Design Patterns will start off by helping you develop a functional way of thinking. We will show you how beneficial the functional-first paradigm is and how to use it to get the optimum results. The book will help you acquire the practical knowledge of the main functional design patterns, the relationship of which with the traditional Gang of Four set is not straightforward. We will take you through pattern matching, immutable data types, and sequences in F#. We will also uncover advanced functional patterns, look at polymorphic functions, typical data crunching techniques, adjusting code through augmentation, and generalization. Lastly, we will take a look at the advanced techniques to equip you with everything you need to write flawless code.

Preface

Exploring type providers


Frankly, I consider type providers as one of the most exciting, powerful, and pragmatic F# features. Ability to apply type providers is, in my opinion, among the strongest arguments for the usage of F# in enterprise software development.

The feature review

Type providers in F# represent a pretty unique practical pattern of manipulating various data sources in a strongly typed manner. This manipulation is accomplished via types, methods, and properties that were derived from the data source features and built at compile-time in a fully automated fashion. The developer is not required to author and/or maintain these automatically provided data manipulation means.

The idea of automatic code generation itself is as old as pyramids, but what makes the difference is versatility, ease of usage, and a painless experience. Those who've ever wrestled with SqlMetal (https://msdn.microsoft.com/en-us/library/bb386987(v=vs.110).aspx) or WSDLTool (https://msdn.microsoft.com/en-us...
