Today we are releasing a free chapter of our CBOX-202: WireBox Dependency Injection & AOP course to the ColdFusion community.  The chapter is an introduction of dependency injection and inversion of control.

We cannot stress the value of using a DI framework in your Object Oriented ColdFusion applications.  There are INCREDIBLE amount of benefits from using a DI framework that you should definitely check this out.  Even if you have never used DI or cared about it, we believe it is fundamental to building sustainable OO ColdFusion applications.  Throughout our experience either in the open source arena or commercial arena, we still see a lack of usage of DI principles in ColdFusion applications and we would like to contribute in terms of education so this topic can be demystified and applied.

There are currently two incredible DI and AOP frameworks for ColdFusion:

• WireBox - http://wiki.coldbox.org/wiki/WireBox.cfm
  
• ColdSpring - http://coldspringframework.org/

Of course, we would recommend WireBox as it is our product.  However, needless to say both libraries are great, proven and very compatible with each other.  The crux of this post is not WireBox is better, or ColdSpring is better, but that using a DI is better.  Forget about how you will implement it, just DO IT!

Anyways, I am incredibly passionate about not only our products, but about ColdFusion and education.  I welcome your thoughts, suggestions and comments.
