title: linq to entites left outer join
body: <p>I am struggling linq to entities left outer join. I have two entities (tables):</p>
  
  <pre><code>Listings 
  {
      ListingID,
      MakeID (nullable)
  }
  
  Makes
  {
      MakeID,
      Description
  }
  </code></pre>
  
  <p>I want to write something like this in LINQ:</p>
  
  <pre><code>select listings.listingID
  ,listings.makeid
  , IsNull(makes.Description, 'NA')
  from listings
  left outer join makes
  on listings.makeid = makes.makeid
  </code></pre>
