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.

A book is like a song, which may usually be referred to by its singer's name, whereas many people are involved in the background to make it happen.
First, I am deeply indebted to my wife, Mona, who has taken all my responsibilities during this period. I understand how hard it was for her to do everything alone that we used to do together.
My special thanks goes to Remo Gloor, the main developers of Ninject, who kindly accepted the final technical review of this book, and other technical reviewers, including Daniel Allen, Matt Duffield, and Ted Winslow for providing valuable feedback.
I would also like to thank my manager, Houman, for being helpful and encouraging, and for understanding how important this book was to me. It would be much difficult to have it done without his support.
Finally, I should acknowledge the whole Packt team, who gave me this opportunity and guided me through this process, including but definitely not limited to, Nikhil Chinnari and Yogesh Dalvi, my commissioning editors, Sneha Modi and Romal Karani, my project coordinators, and Shrutika Kalbag, the author relationship executive for opening a door.

His blog can be found at http://mattduffield.wordpress.com. You can follow him on Twitter at @mattduffield. Matt is also the leader of the Charlotte ALT.NET user group (http://www.meetup.com/charlottealtnet/) and Charlotte Game Dev user group (http://www.meetup.com/Charlotte-Game-Dev/). He is also the Vice President of the Charlotte Enterprise Developers Guild (http://www.developersguild.org/) and also board member of the Carolina Code Camp.
Ted Winslow has been one of those programmers who impressed the likes of NASA and Boeing with his skills behind a keyboard ever since his sixth grade. Even when he isn't working for one of the big names, he's freelancing for multimillion-dollar shops, and considers writing code a way to relax in his downtime. He started writing code while young and did it with little more than a basic starter book and a half-broken computer. Against all odds, he has now a lengthy and respected work history with code chops for which large and small companies hunger. Nowadays, he's spotted helping people in his free time to make sure the young programmers understand and have a chance to live their dream, even when the odds are stacked against them.
I'd like to thank my friends for both the encouragement they've provided during my career and for putting up with me every day. You all mean a lot to me.

Preface
Mastering Ninject for Dependency Injection demonstrates how Ninject facilitates the implementation of Dependency Injection to solve common design problems of real-life applications in a simple and easy-to-understand format. This book will teach you everything you need in order to implement Dependency Injection using Ninject in a real-life project. Not only does it teach the Ninject core framework features which are essential for implementing DI, but it also explores the power of Ninject's most useful extensions, and demonstrates how to apply them in a real-life application.
What this book covers
Chapter 1, Understanding Dependency Injection, introduces Dependency Injection concepts and describes the advantages of using this technique. We will also go through a simple example and implement the principles and patterns related to DI techniques. After understanding what a DI container is, we will discuss why Ninject is a suitable choice.
Chapter 2, Getting Started with Ninject, teaches the user how to add Ninject to a practical project and how to use the basic features of this framework. The chapter starts with an example demonstrating how to set up and use Ninject in a Hello World project. Then, we will talk about how Ninject resolves dependencies and how it manages object lifetime. We will also cover the code-based configuration using Ninject modules and XML-based configuration. The final section of this chapter describes how to configure a large application which includes hundreds of services using Ninject conventions. By the end of this chapter, the user will be able to set up and use the basic features of Ninject.
Chapter 3, Meeting Real-world Requirements, introduces more advanced features of Ninject which are necessary in order to implement DI in real-world situations. The chapter starts with an introduction to some patterns and antipatterns related to Ninject. We will then go through real examples and see how Ninject can solve such kind of problems. By the end of this chapter, the user is expected to know almost all of the significant features of Ninject.
Chapter 4, Ninject in Action, shows how to set up different types of applications using Ninject. We will implement a concrete scenario using a variety of application types, including but not limited to, WPF, ASP .NET MVC, and WCF, to see how to set up and use Ninject for injecting the dependencies. By the end of this chapter, the user should be able to set up and use Ninject for all kinds of described applications.
Chapter 5, Doing More with Extensions, will show how Interception is a solution for cross-cutting concerns, and how to use Mocking Kernel as a test asset. While the core library of Ninject is kept clean and simple, Ninject is a highly extensible DI container, and it is possible to extend its power by using extension plugins. We will also see how Ninject can be extended.
What you need for this book
The examples of the book are written in Microsoft Visual Studio 2012; however, the target framework is set to .NET 4.0 so that they can be easily built using MSBuild and .NET Framework 4.0, even if you do not have Visual Studio 2012.
In the ASP.NET MVC application, we used MVC 3, and Microsoft SQL Server Compact 4.0 is used for SQL Data Layer.
You need an Internet connection to download required references and online packages, such as Ninject and its extensions. Having NuGet package manager on your system facilitates installing of referenced packages, but it is not required, as wherever we need to install such packages, the instruction for manually downloading and referencing the binaries is also provided.
We have also used NUnit for our Unit Tests, which is freely available for download via NuGet or NUnit website.
Who this book is for
This book is for all software developers and architects who are willing to create maintainable, loosely coupled, extensible, and testable applications. Because Ninject targets the .NET platform, this book is not suitable for software developers of other platforms. You should be comfortable with object oriented principals, and have a fair understanding of inheritance and abstraction. Being familiar with design patterns and general concept of unit testing is also a great help, but no knowledge of Dependency Injection is assumed. Although Ninject can be used in any .NET programming languages, the examples of this book are all in C#, so the reader is assumed to be familiar with this language.
