Hi,
the server URI is changed by the ServerInfo constructor in version 100.14. This did not happen in earlier versions.
var serverUrl = new Uri("https://arcgis.com/sharing/rest");
var serverInfo = new ServerInfo(serverUrl);
// serverInfo.ServerUri is now "https://arcgis.com/sharing"
// Passing that URI into e.g. ArcGISPortal.CreateAsync() throws an exception
This causes logins to saved servers (serialized ServerInfo objects for which the ServerURI now is changed when deserialized) in my application to fail.
Please post the exception
An Esri.ArcGISRuntime.Http.ArcGISWebException with the message "Invalid URL" is thrown, but I feel that is not the problem, only a symptom of the changed URL:s.
