How to: Download ClickOnce Application Updates
This example uses the My.Application.Deployment object to download and install the latest version of an application. The example does not update the application unless it is out of date and was deployed as a ClickOnce application.
For more information on ClickOnce applications and how to deploy them, see ClickOnce Deployment and Publishing ClickOnce Applications.
Example
This example downloads and installs the update after using the My.Application.IsNetworkDeployed Property to make sure that the application is deployed using ClickOnce. The Update method does not update the application unless it is out of date. The application has to restart to use the update.
Sub UpdateApplication()
If My.Application.IsNetworkDeployed Then
My.Application.Deployment.Update()
End If
End Sub
