title: Unable to convert runtime connection string to its design-time equivalent
body: <p>I updated to Visual Studio 2013 last week and I can no longer update my Entity Data model through the visual studio designer (.edmx file).  </p>
  
  <p>When I <code>right click &gt; update model from database</code> I now receive this <strong>error</strong>:</p>
  
  <blockquote>
    <p>An Exception of type 'System.ArgumentException' occurred while
    attempting to update from the database.  The exception message is:
    'Unable to convert runtime connection string to its design-time
    equivalent.  Connection string: server=192.168.100.103;user
    id=xxx;password=xxx;database=xxx;persist security info=True'.</p>
  </blockquote>
  
  <p>My connection string is as follows:</p>
  
  <pre><code>  &lt;connectionStrings&gt;
  &lt;add name="DbEntities" connectionString="metadata=res://*/Db.csdl|res://*/Db.ssdl|res://*/Db.msl;provider=MySql.Data.MySqlClient;provider connection string=&amp;quot;server=192.168.100.103;user id=xxx;password=xxx;database=xxx;persist security info=True&amp;quot;" providerName="System.Data.EntityClient" /&gt;
  </code></pre>
  
  <p></p>
  
  <p>The process still works fine in Visual Studio 2012</p>
