SOLID principles

I’ve just loved Hanselman’s show #145, SOLID Principles with Uncle Bob - Robert C. Martin.

I’ve resisted the impulse to join Uncle Bob’s vs Joel Spolsky blog wars. I’m only interested in making reference to Bob’s far-sighted digest of fundamental OO principles. Let me copy them using the order someone have suggested to make it SOLID:

SRP	The Single Responsibility Principle	A class should have one, and only one, reason to change.
OCP	The Open Closed Principle	You should be able to extend a classes behavior, without modifying it.
LSP	The Liskov Substitution Principle	Derived classes must be substitutable for their base classes.
ISP	The Interface Segregation Principle	Make fine grained interfaces that are client specific.
DIP	The Dependency Inversion Principle	Depend on abstractions, not on concretions.

 

This are the class principles. Please follow the link to get the packages and coupling principles.
