How To: Invoke an Application to Restart

I have an application that needs to restart after specific settings have been changed. As of right now I simply issue an information box to the user alerting them that the settings will not take effect until the application has been restarted. But what I really want to do is be able to prompt the user and allow them to choose to restart the application by clicking a button.

Is there a way to have a .Net application restart itself?
