 ABP Framework provides an **object extension system** to allow you to **add extra properties** to an existing object **without modifying** the related class. This allows to extend functionalities implemented by a depended [application module](Modules/Index.md), especially when you want to [extend entities](Customizing-Application-Modules-Extending-Entities.md) and [DTOs](Customizing-Application-Modules-Overriding-Services.md) defined by the module.
