ApplicationChangedEventArgs Class

Provides qualifying information to a callback method when a ApplicationChanged event occurs.

Namespace:  System.Net.PeerToPeer.Collaboration
Assembly:  System.Net (in System.Net.dll)

public class ApplicationChangedEventArgs : EventArgs

An ApplicationChanged event is raised when:

  • A peer starts an application within a collaboration

  • A peer ends an application within a collaboration

  • The PeerContact object that represents a collaborating peer has a change in its properties, such as the associated Nickname

  • The scope of the application is changed on that peer contact's computer

  • A peer moves to a different IP address on the network

Every class that uses the ApplicationChangedEventArgs class requires a PermissionState of Unrestricted. This state is created when the PeerCollaboration object is constructed.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
