Extension Points
Introduction
Extension points allow you to hook functionality into various areas of the Studio Pro IDE. Extension point is a base class that you as an extension developer can inherit from. Your functionality will then be loaded by Studio Pro. These classes all have the *Extension suffix, inherit from ExtensionBase base class, and contain a few virtual or abstract members.
Extension point is the only way you can add a custom behavior to Studio Pro. The rest of the APIs are there only to aid with implementing or expressing these behaviors.
To be injected, your class must be decorated with ExportAttribute like in the example above. This attribute is part of Managed Extensibility Framework that is employed by Studio Pro.
