title: How to get user name, email, etc. from MobileServiceUser?
body: <p>After a lot of digging around I've got my WPF application signing users in via Azure Mobile Service. My Mobile Service is connected to an Azure Active Directory that I have set up. However, when I log the user in with MobileServiceClient.LoginAsync(...) the MobileServiceUser UserId is in an unreadable hash it seems. For example it looks like: "Aad:X3pvh6mmo2AgTyHdCA3Hwn6uBy91rXXXXXXXXXX". What exactly is this?</p>
  
  <p>I'd like to grab the user's display name to use but I can't figure out how.  </p>
