Hi I am not sure if I am missing something or whether this is not within the API which seems short sighted in my opinion.

Can the SDK send a notification to the band from within a background task? This seems to be one of the most useful things to me but when I try I get an error. 'bandClient.NotificationManager.SendMessageAsync' is where it throws an exception. The background task is a timer task.

The background code is simple, I tried it on a background and UI thread.

try

```
            {

                // Get the list of Microsoft Bands paired to the phone.

                IBandInfo[] pairedBands = await BandClientManager.Instance.GetBandsAsync();

                if (pairedBands.Length < 1)

                {

                    deferral.Complete();

                }

                // Connect to Microsoft Band.

                using (IBandClient bandClient = await BandClientManager.Instance.ConnectAsync(pairedBands[0]))

               {

                    await bandClient.NotificationManager.SendMessageAsync(myTileId, "Earnings", currentDollars.ToString(), DateTimeOffset.Now, f);

                }

            }

            catch (Exception ex)

```
