public static ApplicationDeployment CurrentDeployment {

Property Value

Type: System.Deployment.Application.ApplicationDeployment

The current deployment.

Exception Condition

You attempted to call this static property from a non-ClickOnce application.

You cannot create instances of ApplicationDeployment directly in your application; you must retrieve a valid instance through the CurrentDeployment property.

The CurrentDeployment static property is valid only from within an application that was deployed using ClickOnce. Attempts to call this property from non-ClickOnce applications will throw an exception. If you are developing an application that may or may not be deployed using ClickOnce, use the IsNetworkDeployed property to test whether the current program is a ClickOnce application.

The following code example retrieves CurrentDeployment and checks to determine whether the application has been updated in the past three days.

private Boolean CheckForUpdateDue()
    Boolean isUpdateDue = false;

    if (ApplicationDeployment.IsNetworkDeployed)
        ApplicationDeployment ad = ApplicationDeployment.CurrentDeployment;
        TimeSpan updateInterval = DateTime.Now - ad.TimeOfLastUpdateCheck;
        if (updateInterval.Days > 3)
            isUpdateDue = true;

    return (isUpdateDue);
