body: <p>Trying to learn how roles work in ASP.NET.</p>
  
  <p>I've made an empty website an created a database to it with nothing in it. </p>
  
  <p>Here's the connection string:</p>
  
  <pre><code>   &lt;add name="connString"
          connectionString="Data Source=(LocalDB)\v11.0;
          AttachDbFilename='C:\Users\user\Documents\Visual Studio 2012\WebSites\ RolesTutorial\App_Data\base.mdf';
         Integrated Security=True;
         Connect Timeout=30" /&gt;
  </code></pre>
  
  <p>I've installed SQL Express 2012.</p>
  
  <p>What else can I try?</p>
