title: Download public file from Dropbox using VB.NET
body: <p>as written in the title, I'd like to download a public file of Dropbox using VB.NET.
  Obviously I'm not able to do it using WebClient, so I searched some Dropbox API. The problem is that I don't understand as well all those libraries (also because of thirdy parties).</p>
  
  <p>There are a lot of things, like login, upload, file managing, ... while I'd like just the capability to download a file of Dropbox from a given URL. </p>
  
  <p>How can I do it?</p>
