ArcGISPortalManager: Get the Current Active Portal

var active_portal = ArcGISPortalManager.Current.GetActivePortal();

ArcGISPortalManager: Get a list of all your Portals

var portals = ArcGISPortalManager.Current.GetPortals();
//Make a list of all the Uris
var portalUris = portals.Select(p => p.PortalUri.ToString()).ToList();

ArcGISPortalManager: Add a portal to the list of portals

var portalUri = new Uri("http://myportal.esri.com/portal/", UriKind.Absolute);
ArcGISPortalManager.Current.AddPortal(portalUri);

ArcGISPortalManager: Get a portal and Sign In, Set it Active

//Find the portal to sign in with using its Uri...

  //Calling "SignIn" will trigger the OAuth popup if your credentials are
  //not cached (eg from a previous sign in in the session)
  if (portal.SignIn().success)
