Overview of this book

Functional programming makes your application faster, improves performance, and increases your productivity. C# code is written at a higher level of abstraction, so that code will be closer to business requirements, abstracting away many low-level implementation details. This book bridges the language gap for C# developers by showing you how to create and consume functional constructs in C#. We also bridge the domain gap by showing how functional constructs can be applied in business scenarios. We’ll take you through lambda expressions and extension methods, and help you develop a deep understanding of the concepts and practices of LINQ and recursion in C#. By the end of the book, you will be able to write code using the best approach and will be able to perform unit testing in functional programming, changing how you write your applications and revolutionizing your projects.

The task-based asynchronous pattern


The task-based asynchronous pattern (TAP) is a pattern that's used to represent arbitrary asynchronous operations. The concept of this pattern is to represent asynchronous operations in a method and combine the status of the operation and the API that is used to interact with these operators for them to become a single object. The objects are the Task and Task<TResult> types in the System.Threading.Tasks namespace.

Introducing the Task and Task<TResult> classes

The Task and Task<TResult> classes were announced in .NET Framework 4.0 in order to represent an asynchronous operation. It uses threads that are stored in the thread pool but offers the flexibility of how the task is created. We use the Task class when we need to run a method as a task but don't need the return value; otherwise, we use the Task<TResult> class when we need to get the return value.
