How not to do Dependency Injection

Dependency Injection (DI) is not a new concept and has been discussed, blogged, and published many times.  There are a huge number of books out there on the subject.  I've seen many usages and implementations of it used by various clients I've consulted for. 

Like the author of the blog post I refer to below, one of the most common and mis-used, abuses of, and antipatterns I've seen is the wrapping of the DI model in a static container.








I recently found an excellent article that explains in great detail why this is a bad idea and a big anti-pattern - http://www.devtrends.co.uk/blog/how-not-to-do-dependency-injection-the-static-or-singleton-container.

Hopefully, this will help improve your understanding of what DI is and how it should not be used.
