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.

XML configuration


Ninject supports both code-based and XML configuration. An XML module is like a code module that consists of a list of type registrations via Ninject binding. All bindings can be defined in a single XML document or segregated into multiple documents. The only advantage of using XML modules over code modules is that once we have composed such a document, we can still change our type registrations without having to recompile any part of the application. However, XML modules are not as powerful as code modules; so it is recommended to use code modules unless we need this feature. Even in this case, we can only include those bindings for which we need to change the configuration at runtime in our XML module and keep other bindings in code modules.

How to use XML configuration

In order to use XML configuration, we need to add a reference to the Ninject XML extension. It can be added either by installing Ninject.Extensions.Xml via NuGet package manager or by downloading the binary...
