Examples

The following example demonstrates the TransactedInstaller, Install and Uninstall methods of the TransactedInstaller class.

This example provides an implementation similar to that of Installutil.exe (Installer Tool). 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.
