Chapter 11

1. Cross-cutting concerns are those concerns that not part of the business requirements that form the core concerns, but that must be addressed in all areas of the code. AOP stands for Aspect-Oriented Programming.
2. An aspect is an attribute that, when applied to a class, method, property, or parameter, injects code at compile time. You apply an aspect in square brackets before the item it is being applied to.
3. An attribute gives semantic meaning to an item. You apply an attribute in square brackets before the item it is being applied to.
4. Attributes give the code semantic meaning, while aspects remove the boilerplate code so that it is injected at compile time.
5. When the code is being built, the compiler will insert the boilerplate code that the aspect hides from the programmer. This process is known as code weaving.
