      {

          XmlWriterSettings xmlWriterSettings = new XmlWriterSettings();

          xmlWriterSettings.Indent = true;

          using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())

          {

              using (IsolatedStorageFileStream stream = myIsolatedStorage.OpenFile("cost.xml", FileMode.Create))

              {

                

                  XmlSerializer serializer = new XmlSerializer(typeof(ObservableCollection<CostRecord>));

                  using (XmlWriter xmlWriter = XmlWriter.Create(stream, xmlWriterSettings)) 

                    { 

                              serializer.Serialize(xmlWriter, pp); 

                     }
