title: Error when deleting user mvc 4 using SimpleMembership
body: <p>When I try <code>Membership.DeleteUser(string, bool)</code> in a MVC 4 project where I use <code>SimpleMembership</code> provider, I get following error message:</p>
  
  <blockquote>
    <p>"The DELETE statement conflicted with the REFERENCE constraint
    "fk_UserId".  The conflict occurred in database "Conductor_Basic3",
    table "dbo.webpages_UsersInRoles", column 'UserId'. The statement has
    been terminated."</p>
  </blockquote>
  
  <p>The constraints is set and is correct, so I can't really understand the error message. I guess I've missed something here.</p>
  
  <p>Can anyone explain to me this error?</p>
