I mean it from the perspective of use I guess:

When you write a Controller, you put that controller in a project that is part of the "presentation layer" of your application.
All controllers will be in the presentation layer...you won't have any in the business or data access layers.
You have neatly grouped all your controllers into a single area, and they will only be USED by other things in your presentation layer.

When you write a Business object, you put that service in a project that is part of the "business layer" of your application.
All services will be in your business layer...you won't have any in the data access layer or in the presentation layer.
You will transform business objects or graphs into DTO's for transfer accross the wire to your presentation layer and back.
You have neatly grouped all your business objects into a single area, and they will only be USED by other things in your business layer.


Cross-cutting concerns can not be isolated like that:

When you write a logging framework, you put the logger class and its support types in a "shared" area.
Your logging functionality is neatly encapsulated in the shared area of your application.
Your logger will be used in MANY places, accross your layers, including presentation, business, and data access layers.
Your logger's use is not neatly grouped, it is scattered throughout your application, and there is no way to keep usage of logging, a cross-cutting concern, isolated to a single area of your application.
