Ok, so I thought I would upload the code from my TechEd presentation about the SOLID principles here. But before you go and download it, I want to mention that it is a contrived example, and that it might not be “proper” SOLID in all places. However, that is what you get when you have to present an application, and go through all the SOLID principles using it, in 1 hour and 15 minutes…
