    NET developers are only now discovering how DI can improve the quality and maintainability of their. NET code. Dependency Injection in. NET is a comprehensive guide that introduces DI to. NET developers. It covers core concepts and patterns, and introduces important DI frameworks, such as StructureMap, Windsor and Spring. For each framework, it presents examples of its particular usage, as well as examines how the framework relates to the common patterns. Synopsis Featuring examples in Java, Ruby, and C , this in-depth guide explores Dependency Injection, sometimes called Inversion of Control, in fine detail. Synopsis Dependency Injection is an in-depth guide to the current best practices for using the Dependency Injection pattern-the key concept in Spring and the rapidly-growing Google Guice.

    The book presents the core patterns in plain C , so you'll fully understand how DI works. By the end of the book, you'll be comfortable applying this powerful technique in your everyday. NET development. This book is written for C developers. No previous experience with DI or DI frameworks is required. Mark Seemann is a software architect living in Copenhagen.

    Chapter 4 DI patterns 4. Constructor Injection. Chapter 5 DI anti-patterns 5. Control Freak. Chapter 6 DI refactorings 6. Mapping runtime values to Abstractions. Instead of hard-coding dependencies, such as specifying a database driver, you inject a list of services that a component may need.

    The services are then connected by a third party.

    This technique enables you to better manage future changes and other complexity in your software. NET introduces DI and provides a practical guide for applying it in. NET applications. The book presents the core patterns in plain C , so you'll fully understand how DI works. By the end of the book, you'll be comfortable applying this powerful technique in your everyday.

    When combined with convention-based registration it opens for some very powerful constructs. Another interesting development goes in a completely different direction.

    The Hiro container attempts to address the performance overhead that some people seem to be very afraid of. It does that by on the fly auto-generating and compiling the container into IL instructions. This makes it much faster than traditional containers. That's very interesting, but I still think that it attempts to address a problem that doesn't really exist in the first place.

    Apart from that I don't really see a lot of development potential for DI Containers. They seem pretty mature to me, and while there are still more finishing we can apply to them, I can't really see something new and radical on the horizon InfoQ: Have we reached the limits of DI technology or are there any improvements that still need to be made?

    Dependency Injection with Mark Seemann

    As I previously said, DI Containers are already pretty mature. What's really lacking, at least in the. NET world, is an understanding that DI is really about principles and patterns, and not about technology. NET developers we have been raised by Microsoft to believe that every problem can be addressed with a tool.

    When it comes to loose coupling, DI Containers look like enabling technology, but it's really, really important to realize that the solution doesn't lie with the tool. It lies in the understanding that DI or Inversion of Control is a fundamentally different way to reason about and design software. Technology in the shape of a container is totally optional at this point.

    NET at its heart is an object-oriented platform, most developers still write procedural code. There are lots of potential improvements, but the most important ones are to raise awareness of proper OOD.

    InfoQ: Some people are dead set against any form of dependency injection they don't roll themselves. Others obsessively use DI frameworks even when it is clear they aren't appropriate. Where is the balance point between the two extremes? I call this the Composition Root.

    The beauty of it is that once you've isolated composition to the Composition Root the decision about DI Container usage becomes unimportant. When composition is isolated in the Composition Root, making that kind of change isn't particularly hard.

    Although DI should be pervasive in application code, any reference to a specific DI Container should be totally absent. InfoQ: Would you mind going into a more detail about what a composition root is and when you should use one?
