AOP and IoC using Enterprise Library and Unity

with Erik Renaud and Francois Tanguay

Definitions

AOP - Aspect Oriented Programming
IoC - Inversion of Control
Enterprise Library - fills enterprise needs

IoC

• Promotes SoC
• Relies on external mechanism to do the injection
• All about contracts (interfaces)
• Between layers
• Objects shouldn't know each other, just know about each other

AOP

• Promotes SRP
• Cross-cutting

Unity

• Can do singleton with ContainerControlledLifetimeManage parameter
• Thread safe
• Can have multiple mappings with names instances
• Can auto-wire construction dependencies and setter dependencies

PIAB

• You have to be careful with the execution of attributes

EFPRS

• Use DI for wiring
• Use AOP for security and logging

Notes

• Unit Tests
• Arraign, Act, Assert
• Ctrl+E+D - Reformat everything

Tools

• Unity for IoC
• PIAB for AOP
