Injection injection: should we all know this?

Question

One of my friends (he, like me, a .NET / C ++ developer) asked me:

Enabling addiction: should we all know this? Why?

Could you tell:

• Your opinion: do we really need to know this template and how to implement it?
• Good link (link) that could explain why?

Thank you very much.

PS I understand that I ask a lot ... but I can not find a good link myself ...
