title: Could not find an implementation of the query 'Select' not found
body: <p>My error is:</p>
  
  <blockquote>
    <p>Could not find an implementation of the query pattern for source type
    'System.Data.Entity.Database'.  'Select' not found.</p>
  </blockquote>
  
  <p>My relevent code is:</p>
  
  <pre><code>DatabaseEntities db = new DatabaseEntities();   
  var whichUi = from UiType in db.Database
                select  AdvancedUi;
  </code></pre>
  
  <p>I am using the linq import (common answer on other threads).</p>
