None |
This Attribute specifies a Type as implementing a service providing customization or extension of the services provided by any implementation of DesignSurface used by the VSPackage.
DesignSurfaceExtensionAttribute is only used for registration purposes and does not affect how code behaves at runtime.
Instances of this Attribute should only be applied to classes implementing Package for a VSPackage.
Examples
The example below declares that the VSPackage CustomDesigner, provided the class CustomSurfaceExt to customize the design surface it uses.
