title: ClickOnce update cancelled by user and it never asks for an update again
body: <p>I've a <a href="http://en.wikipedia.org/wiki/Windows_Forms" rel="noreferrer">Windows Forms</a> application, and it is deployed through <a href="http://en.wikipedia.org/wiki/ClickOnce" rel="noreferrer">ClickOnce</a>. During launch of the application it checks for an update and prompts the user for the same. If the user choose not to install the update for that session, it doesn't ask anymore. Is this by design or am I missing any setting?</p>
  
  <p>How do I make it prompt the user for an update next time he launches the application?</p>
