title: Outlook add-in ClickOnce update settings
body: <p>I'm trying to deploy Outlook add-in with ClickOnce.
  While setting the update options I noticed that there are fewer options available for Outlook add in project than there are for Win Forms project. For example I cannot specify minimum required version. Why is that? Also, I would like:</p>
  
  <ol>
  <li>to enable manual update</li>
  <li>to ask user if he even wants an update (if it is not required).</li>
  </ol>
  
  <p>1) I tried using System.Deployment.Application and <a href="http://msdn.microsoft.com/en-us/library/system.deployment.application.updatecheckinfo%28v=VS.100%29.aspx" rel="noreferrer">CheckForDetailedUpdate</a>() function but even though update succeeds there are problems installing it: If i restart my plugin it disappears from Outlook, if I don't the old version gets stuck in Outlook (and behaves oddly) although further updates via UNC path suggest that update has been successfully done.</p>
  
  <p>2) Regular publish with no special options added with Mage or MageUI works in itself, but add-in seems to update without asking a user. Googling a bit reveils that people are trying to do the opposite, so I'm kind of puzzled as to why doesn't it prompt for update by default.</p>
  
  <p>I tried editing manifests generated from Visual Studio with MageUI but it generates invalid XML for application manifest (?! - it misses "assemblyIdentity" node in "dependentAssembly" node), and when i add missing nodes from original manifest generated by VS (and update and sign it afterwards), installation complains about assembly hashes being invalid.</p>
  
  <p>How can I deploy Outlook add-in with said requirements?</p>
