copied!<p>I can't talk specifically about converting Spring.NET to Ninject, but in general, all application code should be written to be <strong>DI Container-agnostic</strong>.</p> <p>The best way to think about DI Containers is the <a href="http://en.wikipedia.org/wiki/Hollywood_principle" rel="nofollow noreferrer">Hollywood Principle</a>. In DI terms, it becomes, <strong>don't call the DI Container, it'll call you</strong>.</p> <p>In other words, the best application of DI is to use simple patterns such as <strong>Constructor Injection</strong> and <strong>Abstract Factory</strong>.</p> <p>Most DI Containers worth their salt inherently understand these patterns, so no special, DI Container-specific, jumping through hoops should be needed.</p> <p>This also means that ideally, you should only have DI Container-specific code in a single file in your application. This place is called the <strong>Composition Root</strong>, and this is where the DI Container wires up the entire object graph and gets out of the way.</p> <p>If you follow this principle, you can easily exchange one DI Container for another.</p> <p>The following posts have more details:</p> <ul> <li><a href="https://stackoverflow.com/questions/1475575/where-should-i-do-dependency-injection-with-ninject-2/1475861#1475861">Where should I do Injection with Ninject 2+ (and how do I arrange my Modules?)</a></li> <li><a href="https://stackoverflow.com/questions/1410719/design-where-should-objects-be-registered-when-using-windsor/1410738#1410738">Design - Where should objects be registered when using Windsor</a> </li> </ul>
