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.

WCF applications


In this section, we will implement the Northwind customers scenario using Windows Communication Foundation (WCF). WCF is a highly customizable and extensible framework, and it is possible to configure it to use Ninject service host factories to enable hosting of injectable services. Ninject WCF extensions include all the necessary components.

Now, add a new WCF service application to the Northwind solution, and reference Northwind.Core project. We also need to add reference to the Ninject.Extensions.WCF, Ninject.Web.Common, and Ninject libraries. We can do it either via NuGet, or we can download the binaries from the Ninject page on GitHub. Adding binary references manually requires some manipulations of the Global.asax file in our application. We talked about this approach in the last section. However, adding a reference to Ninject.Extensions.WCF via NuGet will also add other references to the required Ninject packages, and will create the NinjectWebCommon class in the...
