This class identifies entries in the Deployment.ExternalParts collection that represent external library packages required by an application at startup.

The Source property indicates the name of an application library package or an absolute URI that identifies an application library package. Files identified by name only are retrieved from the same server location as the .xap file.

NoteNote:

Files identified by URI must be on the same domain as the .xap file or on a domain with a cross-domain policy file.
