Remarks
Whenever the VSPackage makes use of a design surface, an instance of extensionType object will be used to modify that surface's behavior.
The Type used to construct the DesignSurfaceExtensionAttribute must also be registered as an object provided by the VSPackage, with ProvideObjectAttribute and a service, with ProvideServiceAttribute.
Examples
The example below declares that the VSPackage CustomDesigner, provided the class CustomSurfaceExt to customize the design surface it uses.
[ProvideServiceAttribute(typeof(CustomSurfaceExt))]
[ProvideObjectAttribute(typeof(CustomSurfaceExt))]
[DesignSurfaceExtension(typeof(CustomSurfaceExt))]
class CustomDesigner : Package
