title: Can Entity Framework connection strings reuse an existing connection string?
body: <p>In my configuration files I have a connection string used by a legacy part of the app (using Datasets) and another string for Entity Framework:</p>
  
  <pre><code>&lt;connectionStrings&gt;
      &lt;add name="Database" connectionString="Server=..." /&gt;
      &lt;add name="Entities" connectionString="metadata=.....connection string='Server=..." /&gt;
  &lt;/connectionStrings&gt;
  </code></pre>
  
  <p>This means the server name, database name etc. are specified twice. I'd like to tell the EF connection string to reuse the first string - is this possible?</p>
