title: LINQ to SQL returning old data after an update
body: <p>I have an app that uses LINQ to SQL to connect to database. I have a problem getting LINQ to SQL to return correct new update data.</p>
  
  <p>What happened is that, I changed a field on UI, LINQ to SQL generated update statement, and stored the new data in database. However, LINQ to SQL keeps returning the old data after that, I have to stop and restart IIS to get the new updated data.</p>
  
  <p><strong>Update</strong></p>
  
  <p>Please note that the old data is returned from LINQ to SQL.</p>
  
  <p>Any idea?</p>
