title: distinct with LINQ
body: <pre><code> var sourceId =
              (from workstation in db.station
               join letter in db.letter on workstation.id equals letter.Site_Id
               where ThatDate &lt; DateTime.Now.AddYears(-1)
               select workstatio).ToList();
  </code></pre>
  
  <p>This produces a list which will print out repeats if more than one, how can I use .distinct?</p>
  
  <p>Please advise, thanks</p>
