The My.Application.Deployment property returns the application's ClickOnce ApplicationDeployment object. The ApplicationDeployment object provides support for updating the current deployment programmatically as well as support for the on-demand download of files. For more information on ClickOnce applications and how to deploy them, see ClickOnce Security and Deployment and Publishing ClickOnce Applications.
