Linking Classes Together
WMI providers are usually designed to provide information about a specific managed object on a single computer. If there is a common property that can serve as a key to uniquely identify all the different source instances, then use the View Provider to combine properties from different classes, namespaces, or computers into a single class.
You must first register the View Provider. After registration, you can create the following types of view classes:
Instances of different classes connected by a common property value.
Views of existing association classes across the namespace boundary.
Union of one or more instances.
