How can I force an oneclick application to restart and update?

Question

I have a OneClick WPF application deployed but unfortunately I am having trouble updating the application.Previously, I was using Application.Deployemnt's update() function, but since Application.Deployment is no longer available, how do I go about forcing the application to restart to trigger the update?

So far I tried System.Windows.Forms.Application.Restart(); and string currentPath = Process.GetCurrentProcess().MainModule.FileName; Process.Start(currentPath);

but this is just restarting the application, not triggering the update to the new published version.
