These principles include maintaining separation of concerns, using abstraction to implement loose coupling between layers and components, implementing service location capabilities, and managing crosscutting concerns such as logging and security. While these may seem to be desirable but unrelated aims, one technique can help you to apply several design principles easily. The Dependency Inversion principle implies separation of concerns through abstractions rather than concrete implementations. In terms of design patterns, you can achieve this by applying the Inversion of Control (IoC) pattern and its related pattern, Dependency Injection (DI).
The theory is simple enough. Instead of specifying at design time the actual concrete type that each class or component will use to perform some activity or process, you arrange for these classes or components to retrieve the appropriate object from a container that you previously configured with type maps and registered types.
Dependency Injection is great for achieving loose coupling of components. There are a lot of tools available that can be used for injecting dependencies. A list of such tools can be found on the Wikipedia page as well as on the Clean Code Developer Tools page.
