title: SQL Server Object Explorer doesn't show my database
body: <p>I started a MVC project on VS2012, created my models, my controllers and my views. I'm using Entity Framework code-first, so I've enabled migrations and I'm updating the database accordingly to the changes in the code.
  The pages run just fine, the database is working properly, the data is being retrieved as it should, so functionally, everything is fine.</p>
  
  <p>The problem is that I see no connection string in my web.config:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

  <p>Nor do the database shows up in the SQL Server Object Explorer...
  I've already checked <a href="https://stackoverflow.com/questions/20200162/ssdt-on-visual-studio-2012-broken-then-fixed-broken-again-also-broken-on-vs2013">this answer</a>, but the server on my Object Explorer was already the correct.</p>
