F# High Performance

By: Eriawan Kusumawardhono

Overview of this book

F# is a functional programming language and is used in enterprise applications that demand high performance. It has its own unique trait: it is a functional programming language and has OOP support at the same time. This book will help you make F# applications run faster with examples you can easily break down and take into your own work. You will be able to assess the performance of the program and identify bottlenecks. Beginning with a gentle overview of concurrency features in F#, you will get to know the advanced topics of concurrency optimizations in F#, such as F# message passing agent of MailboxProcessor and further interoperation with .NET TPL. Based on this knowledge, you will be able to enhance the performance optimizations when implementing and using other F# language features. The book also covers optimization techniques by using F# best practices and F# libraries. You will learn how the concepts of concurrency and parallel programming will help in improving the performance. With this, you would be able to take advantage of multi-core processors and track memory leaks, root causes, and CPU issues. Finally, you will be able to test their applications to achieve scalability.

Preface

Implementing your own type provider


We already have enough knowledge on what a type provider is, the building blocks, and the nature of type providers, also understanding the nature of type provider implementations, including the implementation strategies, as we went deeper.

To ease the experience and our type provider building mindset, a real experience of quickly using it from existing samples has proven to be very useful. We have increased our intuition on how type provider works using samples from F# 4.0 built-in type provider features, FSharp.Data.TypeProvider.

Implementing your own type provider again is quite a bit tedious, especially when we are dealing with generative type providers as our choice of strategy.

The following are the common steps of implementing your own type provider:

  1. Declare your type provider. The type provider must be public.

  2. Mark your type provider's type with TypeProviderAttribute. You can simply use the abbreviated TypeProvider. This attribute is available in Microsoft...
