CurrentVersion Property

ApplicationDeployment.CurrentVersion Property

Gets the version of the deployment for the current running instance of the application.

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

public Version CurrentVersion { get; }

Property Value

Type: System.Version
The current deployment version.

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

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

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);
