title: The connection string 'MyConnection' in the application's configuration file does not contain the required providerName attribute."
body: <p>I use <code>Entity Framework Code First</code>,</p>
  
  <p>My connection string is in a configuration file:</p>
  
  <pre><code>&lt;connectionStrings&gt;
      &lt;clear/&gt;
      &lt;add name="ApplicationServices" connectionString="Data Source=PC-X;Initial Catalog=MYdb;Integrated Security=True"/&gt;
    &lt;/connectionStrings&gt;
  </code></pre>
  
  <p>When I try to access the data (something that should create the DB) is falling with the following error:</p>
  
  <blockquote>
    <p>The connection string 'ApplicationServices' in the application's
    configuration file does not contain the required providerName
    attribute."</p>
  </blockquote>
  
  <p>What am I missing?</p>
