title: EF 5.0 without config details
body: <ol>
  <li>How can we make use EF code first without the below configuration but rather only a DB connection string, just like traditional ADO.net and dataset.</li>
  <li>How can EF 5.0 reflect underlying table structure at runtime? like ADO.NET dataset.</li>
  </ol>
  
  <p>Configuration:</p>
  
  <pre><code>  &lt;configSections&gt;
      &lt;!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --&gt;
      &lt;section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /&gt;
    &lt;/configSections&gt;
    &lt;entityFramework&gt;
      &lt;defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework"&gt;
        &lt;parameters&gt;
          &lt;parameter value="v11.0" /&gt;
        &lt;/parameters&gt;
      &lt;/defaultConnectionFactory&gt;
    &lt;/entityFramework&gt;
