Body
I want to be able to play an audio file (a sound basically) from the background agent. I am using the following two approaches : 1) <pre><code> SoundEffectInstance ClockTickInstance; StreamResourceInfo ClockTickStream; SoundEffect ClockTickSound; try { ClockTickStream = Application.GetResourceStream(new Uri( @"AudioFiles/NewHighScore.wav", UriKind.Relative)); ClockTickSound = SoundEffect.FromStream(ClockTickStream.Stream); ClockTickInstance = ClockTickSound.CreateInstance(); ClockTickInstance.IsLooped = true; ClockTickInstance.Volume = 1.0f; ClockTickInstance.Pitch = 1.0f; ClockTickInstance.Play(); ClockTickInstance.Stop(); } </code></pre> OR 2) <pre><code>var localFolder = Package.Current.InstalledLocation; Stream fileStream = await localFolder.OpenStreamForReadAsync("NewHighScore.wav"); byte[] buffer = new byte[fileStream.Length]; fileStream.Read(buffer, 0, System.Convert.ToInt32(fileStream.Length)); fileStream.Close(); SoundEffect soundefct = new SoundEffect(buffer, 16000, AudioChannels.Mono); FrameworkDispatcher.Update(); soundefct.Play(); </code></pre> When i run the code from the xaml.cs file (i.e. from the foreground app) evrything works fine and the sound is played. But from the background agent, the code runs but no sound is heard. What could be the problem? the following article shows the list of APIs that can be used while the app is running in the background - <a href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj662941(v=vs.105).aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj662941(v=vs.105).aspx</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
