How can I open Windows Explorer to a certain directory from within a WPF app?

Question

In a WPF application, when a user clicks on a button I want to open the Windows explorer to a certain directory, how do I do that?

I would expect something like this

Answer 1

Process.Start("explorer.exe" , @"C:\Users");

I had to use this, the other way of just specifying the tgt dir would shut the explorer window when my application terminated.
