Mastering Ninject for Dependency Injection

By: Daniel Baharestani

Overview of this book

Dependency injection is an approach to creating loosely coupled applications. Maintainability, testability, and extensibility are just a few advantages of loose coupling. Ninject is a software library which automates almost everything that we need in order to implement a dependency injection pattern. Mastering Ninject for Dependency Injection will teach you everything you need to know in order to implement dependency injection using Ninject in a real-life project. Not only does it teach you about Ninject core framework features that are essential for implementing dependency injection, but it also explores the power of Ninject's most useful extensions and demonstrates how to apply them. Mastering Ninject for Dependency Injection starts by introducing you to dependency injection and what it's meant for with the help of sufficient examples. Eventually, you'll learn how to integrate Ninject into your practical project and how to use its basic features. Also, you will go through scenarios wherein advanced features of Ninject, such as Multi-binding, Contextual binding, providers, factories and so on, come into play. As you progress, Mastering Ninject for Dependency Injection will show you how to create a multilayer application that demonstrates the use of Ninject on different application types such as MVC, WPF, WCF, and so on. Finally, you will learn the benefits of using the powerful extensions of Ninject.

Why use Ninject?


Ninject is a lightweight Dependency Injection framework for .NET applications. It helps you split your application into a collection of loosely-coupled, highly-cohesive pieces, and then glues them back together in a flexible manner. By using Ninject to support your software's architecture, your code will become easier to write, reuse, test, and modify. Instead of relying on reflection for invocation, Ninject takes advantage of lightweight code generation in the CLR (Common Language Runtime). This can result in a dramatic (8-50x) improvement in performance in many situations. Ninject includes many advanced features. For example, Ninject was the first dependency injector to support contextual binding, in which a different concrete implementation of a service may be injected, depending on the context in which it is requested. Ninject supports most major facilities offered by the competing frameworks (although, many such elements live in extensions: plugin modules that layer on facilities on top of the core). You can have a look at the Ninject official wiki at https://github.com/ninject/ninject/wiki for a more detailed list of Ninject features which makes it one of the top DI containers.
