title: WPF SaveFileDialog that permits selection of folder, not just file
body: <p>I need a control like <code>SaveFileDialog</code> that lets me choose a <strong><em>directory</em></strong> instead of a file. It should also let me specify the directory by pasting text. SaveFileDialog does not allow this.</p>
  
  <p>I have tried <code>FolderBrowserDialog</code>, but it does not meet my requirements because it does not support pasting the directory path as text. Some of the directory I'm working with may be nested 10 levels or more, so being forced to navigate via point-and-click is not enough.</p>
  
  <p>Thanks in advance.</p>
