title: Image (?) File(?) Metadata(?) Properties(?)
body: <p>Sorry for the question marks, but a simple (I think) question has an impossible solution.
  From file system, if I click on an image file "Properties | Details tab" I access to many metadata.
  I need to access from a WPF application to the Description properties (Title, Subject, Rating, Tag and Comment). In particular Tag.</p>
  
  <p>I have found a lot of articles, many are very old. A few in WPF and Imaging library. But no one access to that properties. So the question marks: are these properties on image? On file system? I think they are on the image..I don0t undestand where are these properties and why is so difficult to access...</p>
  
  <p>Can someone help me?</p>
  
  <p>Thanks in advance,</p>
