title: Adding Entity Framework configuration in Visual Studio extension
body: <p>Here's my solution architecture:</p>
  
  <ul>
  <li>VM (class lib)                   => references SQLite.</li>
  <li>App (WPF Desktop App)            => references VM.</li>
  <li>VSIX (Visual Studio extension)   => references VM.</li>
  </ul>
  
  <p>I have copied EF providers related stuff from <code>app.config</code> of VM project to both desktop app and VSIX projects. The desktop app works fine whereas the VSIX project throws the following exception:</p>
  
  <blockquote>
    <p>No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SQLite.EF6'. Make sure the provider is registered in the 'entityFramework' section of the application config file.</p>
  </blockquote>
  
  <p>Is there something special I need to do in case of extension projects?</p>
