copied!<p>In my opinion the number one benefit of an IoC is the ability to centralize the configuration of your dependencies.</p> <p>If you're currently using Dependency injection your code might look like this</p> <pre class="lang-cs prettyprint-override"><code>public class CustomerPresenter { public CustomerPresenter() : this(new CustomerView(), new CustomerService()) {} public CustomerPresenter(ICustomerView view, ICustomerService service) { // init view/service fields } // readonly view/service fields } </code></pre> <p>If you used a static IoC class, as opposed to the, IMHO the more confusing, configuration files, you could have something like this:</p> <pre class="lang-cs prettyprint-override"><code>public class CustomerPresenter { public CustomerPresenter() : this(IoC.Resolve<ICustomerView>(), IoC.Resolve<ICustomerService>()) {} public CustomerPresenter(ICustomerView view, ICustomerService service) { // init view/service fields } // readonly view/service fields } </code></pre> <p>Then, your Static IoC class would look like this, I'm using Unity here.</p> <pre class="lang-cs prettyprint-override"><code>public static IoC { private static readonly IUnityContainer _container; static IoC() { InitializeIoC(); } static void InitializeIoC() { _container = new UnityContainer(); _container.RegisterType<ICustomerView, CustomerView>(); _container.RegisterType<ICustomerService, CustomerService>(); // all other RegisterTypes and RegisterInstances can go here in one file. // one place to change dependencies is good. } } </code></pre>
