Examples

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

public:
    bool CheckForUpdateDue()
    {
        bool isUpdateDue = false;

        if (ApplicationDeployment::IsNetworkDeployed)
        {
            ApplicationDeployment^ dueAppDeployment =
                ApplicationDeployment::CurrentDeployment;
            TimeSpan^ updateInterval =
                DateTime::Now - dueAppDeployment->TimeOfLastUpdateCheck;
            if (updateInterval->Days >= 3)
            {
                isUpdateDue = true;
            }
        }

        return (isUpdateDue);
    }

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);
}

Private Function CheckForUpdateDue() As Boolean
    Dim isUpdateDue As Boolean = False

    If (ApplicationDeployment.IsNetworkDeployed) Then
        Dim AD As ApplicationDeployment = ApplicationDeployment.CurrentDeployment
        Dim updateInterval As TimeSpan = DateTime.Now - AD.TimeOfLastUpdateCheck
        If (updateInterval.Days > 3) Then
            isUpdateDue = True
        End If
    End If

    CheckForUpdateDue = isUpdateDue
End Function

Remarks

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.
