title: The type initializer for 'System.Data.Entity.Internal.AppConfig' threw an exception. After downgrading to entity framework 5 from 6
body: <p>I'm trying to get Entity Framework working with and Oracle database.</p>
  
  <p>I originally had entity framework 6 installed but now I've downgraded to EF 5 because I've read EF6 doesn't work with ODP.NET.</p>
  
  <pre><code>  &lt;configSections&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;!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --&gt;
    &lt;/configSections&gt;
  </code></pre>
  
  <p>This is my app config, config section. I've reinstalled EF 5 on all my projects but keep getting this error.</p>
