title: UWP Contacts, Contact Lists and Contact Timelines
body: <p>I have found good information from the UWP sample repo on GitHub for how to create contacts for a UWP app as well as contact list annotations.</p>
  
  <p>What I can't find is how I can add line items to the contact's timeline in the same way that the mail program adds recently received emails for that contact or Skype Preview adds recently received calls or messages.</p>
  
  <p>Also, how do you make a contact list readonly to the user? I want the contact list to be updated only by the app. I'm referring to a contact list that is added to the People app. These contacts can then be linked w/ other contacts in the people hub.</p>
