IoCTasks

Intro

This solution contains a set of projects which should help you understand to following topics:

• IoC/DI (Inversion Of Control/Dependency Injection principles).
• IoC containers.
• Microsoft Unity IoC container.
• It also touches on highly related topic which is Unit testing.

Motivation

• Provide 'hands-on experience' course on the topics above in form of small coding tasks.
• Help to guys on the team to understand the topic.
• Deliver sample solutions for all tasks which can serve as a reference with intent:
  • At first try to resolve tasks on your own.
  • If you will get stuck feel free use appropriate sample solution to unblock yourself.
  • After you solved it on your own, look at the sample solution to make sure we understand it in the same way.

Sources

• The best theoretical source on inversion of control and dependency injection is probably [Martin Fowler's article] (http://martinfowler.com/articles/injection.html)
• There is also very useful [StackExchange thread] (http://programmers.stackexchange.com/a/205686) which is dedicated to the above mentioned article and is very helpful in understanding that IoC can have many forms
• The rest of sources includes:
  • [MSDN article] (http://msdn.microsoft.com/en-us/library/ff921087.aspx)
  • Two CodeProject articles, [DI vs IoC] (http://www.codeproject.com/Articles/592372/Dependency-Injection-DI-vs-Inversion-of-Control-IO) and [IoC with examples] (http://www.codeproject.com/Articles/380748/Inversion-of-Control-Overview-with-Examples)
  • two PluralSight courses, [one dedicated to IoC in general] (http://www.pluralsight.com/courses/inversion-of-control) and [the other in regards of ASP.NET MVC] (http://www.pluralsight.com/courses/ioc-aspdotnet-mvc4)
  • short article about [introducing IoC into existing codebases] (http://kozmic.net/2012/10/23/ioc-container-solves-a-problem-you-might-not-have-but-its-a-nice-problem-to-have/)
• Microsoft Unity reference guide on MSDN:
  • [MSDN] (http://msdn.microsoft.com/en-us/library/dn178463%28v=pandp.30%29.aspx)
• NUnit unit testing framework:
  • [NUnit] (http://www.nunit.org)
• Moq mocking framework:
  • [Moq] (https://github.com/Moq/moq4)

How to use projects

• Each project is a prepared coding task.
• Each project contains README.md file which provides brief summary of the topic and goals for the task.
• For additional information look into the Microsoft Unity documentation (goal of this project is not to provide reference guide to MS Unity API).
• Simply clone this project (or download it as a .ZIP file) and attempt to solve all individual tasks.
  • If you need some help just reference to [solutions repository] (https://github.com/IoCHowTo/IoCTasksSolutions).
• Open the solution in VS2012+ and compile it. The compilation would download dependencies from Nuget (such as Microsoft Unity).
• If you are aware of some interesting challenge in the area feel free to propose a sample tasks with sample solution in form of pull request.
