Application.Restart Method ()
Shuts down the application and starts a new instance immediately.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Your code is not a Windows Forms application. You cannot call this method in this context.
The most common reason for calling Restart is to start a new version of the application that you have downloaded through ClickOnce using the Update or UpdateAsync method.
Applications are restarted in the context in which they were initially run. If your application was started using a URL pointing directly to the application's main executable file, it will be restarted using the same URL. If your application is a ClickOnce application, it will be restarted using ClickOnce.
If your application was originally supplied command-line options when it first executed,will launch the application again with the same options.
