When is Dependency Injection too Much?

I’ve been working on NopCommerce for the past few weeks and I keep finding interesting code. The following constructor signature makes me ask a very simple question with a very complicated answer…

“When is dependency injection too much?”

• Is there a better approach?
• Could MEF (Managed Extensibility Framework) have been used instead?
• Does this code violate the SOLID Principles?
• How hard will it be to maintain this solution in the long run?

Bottom line, is that when I see code like this, I can’t help myself… I have to ask

“Could this have been done differently?”
