title: Data table is not generated when I attempt to add a connection
body: <p>I'm following a guide for creating a simple code-first MVC, which uses data context scaffolding.  After creating a model class file and adding a scaffolded item to the project, it instructs me to go to server explorer, hit "new connection", enter (localdb)\mssqllocaldb and from there, select my database name (PlanetContext (CodeFirstFinal.Models).  After hitting "ok", I should be able to expand the tables in my server explorer and see the planet data table.  However, my tables folder is empty.  I followed the tutorial to the letter, so I'm unsure why this is happening. </p>
  
  <p>Here is the code in my model:</p>
  
  <pre><code>namespace CodeFirstFinal4.Models
  {
      public class Planet
      {
          public int PlanetID { get; set; }
          public string Name { get; set; }
  
      }
  
      public class PlanetContext: DbContext
      {
          public DbSet&lt;Planet&gt; Categories { get; set; }
  
      }
  }
  </code></pre>
  
  <p>As this is a very simple app, this is the only code so far, besides the scaffolded view. (For that, I right-clicked my project, selected "add scaffolded item" and MVC 5 Controller with views using EntityFramework.  I then entered my model class, which is:
  Planet (CodeFirstFinal4.Models) </p>
  
  <p>and my data context class, which is:  PlanetContext (CodeFirstFinal4.Models).</p>
  
  <p>I'm not sure how helpful this information is, but I'm including it in case it helps.  I'm pretty sure that the MvcScaffolding package is installed correctly, as well as EntityFramework.  However, I simply can't get the data table to be generated after right clicking 'connect to database' under server explorer, entering my local server name, and selecting the database.  Below is a screenshot of the tutorial, where his table shows up under the tables folder, within server explorer.  Does anyone know what might be causing the failed generation of my own data table?</p>
