title: The schema update is terminating because data loss might occur
body: <p>I keep bumping into this error that is usually caused by some mistake I have made while building an application in <code>Lightswitch</code>.  It is usually associated with relationships.  I am ususally moving along and done a number of things before I publish the app and see the error.  By this time it is difficult to calulate what I did wrong.  Is there a way I trace this error back to see what I need to change in the tables?</p>
