I have oAuth working - however the current user always comes back as null after I type my username and password:
IdentityManager.Current.OAuthAuthorizeHandler = new Esri.ArcGISRuntime.Toolkit.Security.OAuthAuthorizeHandler();
var item = await Esri.ArcGISRuntime.Portal.ArcGISPortalItem.CreateAsync(portal, "367f0a8a210d49218f7cb7bf5da994c8");
var portal = await Esri.ArcGISRuntime.Portal.ArcGISPortal.CreateAsync();
var user = portal.CurrentUser; //comes back null
How do I get the current user without re-authenticating?
