Property Value
A Boolean that represents whether the application was deployed from a network. The value is True if the current application was deployed from a network; otherwise the value is False.
Remarks
The My.Application.IsNetworkDeployed property indicates whether the application was deployed from a network using ClickOnce. For more information on ClickOnce applications, see ClickOnce Deployment.
You should check that this property is True before accessing the My.Application.Deployment Property. Otherwise, if the application is not deployed from a network using ClickOnce, reading the My.Application.Deployment property results in an InvalidDeploymentException exception.
For more information on configuring ClickOnce, see Publishing ClickOnce Applications. For more information on deploying a ClickOnce application, see How to: Publish a ClickOnce Application.
