ApplicationDeployment.UpdatedVersion Property


Gets the version of the update that was recently downloaded.

Namespace:   System.Deployment.Application
Assembly:  System.Deployment (in System.Deployment.dll)

public Version UpdatedVersion {
	[PermissionSetAttribute(SecurityAction.Assert, Name = "FullTrust")]

Property Value

Type: System.Version

The Version describing the version of the update.

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.

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

public Boolean IsNewVersionAvailable()
    Boolean isRestartRequired = false;

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

    return (isRestartRequired);
