TransactedInstaller Class
Assembly: System.Configuration.Install (in system.configuration.install.dll)
To run installers in a transaction, add them to the Installers property of this TransactedInstaller instance.
The following example demonstrates the TransactedInstaller, Install and Uninstall methods of the TransactedInstaller class.
This example provides an implementation similar to that of Installer Tool (Installutil.exe). It installs assemblies with the options preceding that particular assembly. If an option is not specified for an assembly, the previous assembly's options are used if there is a previous assembly in the list. If either the "/u" or "/uninstall" option is specified, the assemblies are uninstalled. If the "/?" or "/help" option is provided, the help information is displayed to the console.
