SOLID is an acronym for

• Single Responsibility Principle,
• Open/Closed Principle,
• Liskov Substitution Principle,
• Interface Segregation Principle, and
• Dependency Inversion Principle.

In this session, we’ll introduce SOLID principles which help developers to

• simplify the implementation,
• minimize the impact of change, and
• facilitate testing

by emphasizing high cohesion and low coupling using techniques centered around abstraction, inheritance and polymorphism. In addition, we’ll introduce the Microsoft Unity Application Block, a lightweight, extensible dependency injection container for applying the Dependency Inversion Principle.
