Installer::OnBeforeRollback Method
Raises the BeforeRollback event.
Assembly: System.Configuration.Install (in System.Configuration.Install.dll)
Parameters
- savedState

An IDictionary that contains the state of the computer before the installers in the Installers property are rolled back.
This method is called before the Rollback methods of the installers in this instance's InstallerCollection are called.
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnBeforeRollback method allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to InheritorsWhen overriding OnBeforeRollback in a derived class, be sure to call the base class's OnBeforeRollback method so that registered delegates receive the event.
