Examples

The following code example defines a method that determines whether ClickOnce has updated the application.

public:
    bool IsNewVersionAvailable()
    {
        bool isRestartRequired = false;

        if (ApplicationDeployment::IsNetworkDeployed)
        {
            ApplicationDeployment^ restartAppDeployment =
                ApplicationDeployment::CurrentDeployment;
            if (restartAppDeployment->UpdatedVersion > 
                restartAppDeployment->CurrentVersion)
            {
                isRestartRequired = true;
            }
        }

        return (isRestartRequired);
    }

public Boolean IsNewVersionAvailable()
{
    Boolean isRestartRequired = false;

    if (ApplicationDeployment.IsNetworkDeployed)
    {
        ApplicationDeployment ad = ApplicationDeployment.CurrentDeployment;
        if (ad.UpdatedVersion > ad.CurrentVersion)
        {
            isRestartRequired = true;
        }
    }

    return (isRestartRequired);
}

Public Function IsNewVersionAvailable() As Boolean
    Dim isRestartRequired As Boolean = False

    If (ApplicationDeployment.IsNetworkDeployed) Then
        Dim AD As ApplicationDeployment = ApplicationDeployment.CurrentDeployment
        If (AD.UpdatedVersion > AD.CurrentVersion) Then
            isRestartRequired = True
        End If
    End If

    IsNewVersionAvailable = isRestartRequired
End Function

Remarks

UpdatedVersion differs from CurrentVersion if a new update has been installed but you have not yet called Restart on the Application. If the application's deployment manifest is configured to perform automatic updates, you can compare these two values to determine whether you should restart the application.

If the application has not been updated, UpdatedVersion returns the same value as CurrentVersion.
