Dependency Injection (DI) and inversion of control (IoC) have been hot topics lately due to the popularity of lightweight IoC containers such as Spring and Pico. In this presentation, we will examine the ways in which the use of dependency injection affects architecture and design. We will examine the positive and negative consequences of using DI as a design technique and how it affects configuration, testing, and maintainability. This talk focuses on the technique rather than any particular container.
