The SOLID principles are something that everyone agrees are a Good Thing and they are definitely doing ... but few people can name all five at the first attempt and fewer still can say what they are, why each is important, or why we as developers should be using them.

In this session I want to explore the detail of each of the five principles, what they claim, and what they are actually about. I will propose some better approaches to reasoning about, designing and writing the code you deal with every day.

There won't be a quiz on the five principles but there may be a little bit of history along the way.

Hopefully not too ranty, targetted at newer developers who are sold SOLID as a thing to aspire to but don't have the experience to know what's wrong with it.
