title: Visual Studio 2017 doesn't show tooltip on debugger
body: <p>I recently downloaded visual studio 2017 because developing xamarin apps, has many utilities in more, that make me comfortable.</p>
  
  <p>That said, I wonder if any of you have already downloaded and if the tooltip problem in debugging, I do not see anything.
  And so it is impossible to work. But panel "Locals" work.
  I searched online but it is still too early to find help.
  If anyone has had the same problem and solved tell me.
  Thank you.</p>
