Raises the BeforeInstall event.

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The 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 Inheritors
When overriding in a derived class, be sure to call the base class's method so that registered delegates receive the event.
The following example demonstrates the method. This method is overridden in the derived class. Space is provided to add steps to be done before the installation in the method.
' Override the 'OnBeforeInstall' method. Protected Overrides Sub OnBeforeInstall(savedState As IDictionary) MyBase.OnBeforeInstall(savedState) ' Add steps to be done before the installation starts. Console.WriteLine("OnBeforeInstall method of MyInstaller called") End Sub 'OnBeforeInstall
