title: Update model from database in entity framework is not working
body: <p>If any changes have made on the datatype or constraints(e.g. not null - null) of a particular column in table and performing <code>Update model from database</code> (Refresh a particular table) in entity framework is not updating the entity model.</p>
  
  <p>Each time I have to delete and re-create the table manually. </p>
  
  <p>Is this only solution? or any other best way to do this?</p>
