c# - OpenStreamForWriteAsync Doesn't finish -


i trying save serialised object file. when call openstreamforwriteasync method ui locks , process never seems end. not sure doing wrong here.

            public async task<string> save(string filename)     {         memorystream ms = new memorystream();         var serializer = new datacontractserializer(typeof(settings));          serializer.writeobject(ms, this);          ms.position = 0;          try         {             using (var fms = await applicationdata.current.localfolder.openstreamforwriteasync(filename, creationcollisionoption.replaceexisting))             {                 serializer.writeobject(fms, this);                 return "saved successfully";             }         }         catch         {             return "could not save.";         }      }

this first question on stackoverflow, have been long time learner. appreciated.

found problem. not awaiting when calling method. needed call method using:

string result =  await settings.save("settings.xml");

will rename method saveasync reminder.
