{
    try
    {               
        base.Uninstall(savedState);

Application installation is not something that we need to manage manually in the .NET Framework. It provides multiple installation options, so you do not have to manually install or uninstall your applications. The two main installation options the Framework are:

1. ClickOnce Deployment
2. Setup Projects
