title: What is the connection string for localdb for version 11
body: <p>I'm trying to do the Code First Walkthrough of the entity framework ( <a href="http://blogs.msdn.com/b/adonet/archive/2011/09/28/ef-4-2-code-first-walkthrough.aspx">http://blogs.msdn.com/b/adonet/archive/2011/09/28/ef-4-2-code-first-walkthrough.aspx</a> ).</p>
  
  <p>I have the latest SQL Server Express and when I check my versions available via command line (<em>sqllocaldb info</em>): I see localdbApp1 and v11.0.  When I try to run the walkthrough with a few minor tweaks, I get a can't connect error.</p>
  
  <p>My app.config looks like this:</p>
  
  <pre><code>&lt;parameter value="Server=(LocalDB)\v11.0; Integrated Security=True; MultipleActiveResultSets=True" /&gt;
  </code></pre>
  
  <p>I wrote a simple connection test like below and the code returns the same SQL Connection error ((provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)). </p>
  
  <pre><code>new System.Data.SqlClient.SqlConnection("Data Source=(LocalDB)\v11.0; Integrated Security=True; MultipleActiveResultSets=True").Open();
  </code></pre>
  
  <p>I've tried replacing <code>"Data Source=..."</code> with <code>"Server=..."</code> but to no avail there.</p>
  
  <p>Any ideas what the connection string should be?</p>
