class Apps: INotifyPropertyChanged{

        ServiceReference1.AssetManagerServiceClient client;
        ObservableCollection<string> availableType;

        public ObservableCollection<string> AvailableTypes
        {
            get
            {
                if (availableType == null)
                {
                    availableType = new ObservableCollection<string>();

                }
                client = new ServiceReference1.AssetManagerServiceClient();
                List<string> AssestList = client.GetAppIds().ToList<string>();

                foreach (string appid in AssestList)
                {
                    availableType.Add(appid);
                }

                return availableType;
            }

            set
            {
                availableType = value;
                NotifyPropertyChanged("AvailableTypes");
            }
        }

        public event PropertyChangedEventHandler PropertyChanged;

        private void NotifyPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
