从后台音频代理更新动态磁贴?

我知道您可以使用 PeriodicTask 的 ShellTile 更新 Liva Tils.是否可以更新后台音频代理的实时磁贴?
I know that you can update Liva Tils with ShellTile of PeriodicTask. is it possible to update the live tiles of background audio agent?
例如,当曲目更改为实时磁贴上的标题曲目时,我想这样做.这可能吗?
I want to do, for example, when the track changed to the title track on the live tile. Is this possible?
只是不想做后台代理的一些应用:代理音频甚至定期后台代理.这么重的负载会不会影响电池寿命?
Just did not want to do would have been a few applications of background agents: agent audio and even periodic background agent. Would not this heavy load and impact on battery life?
更新:BackgroundAudioPlayer是这样试的:
Update:BackgroundAudioPlayer tried in this way:
ShellTile apptile = ShellTile.ActiveTiles.First();
StandardTileData appTileData = new StandardTileData();
appTileData.Title = "Title App";
appTileData.Count = 5;
appTileData.BackgroundImage = new Uri("/front.png", UriKind.RelativeOrAbsolute);
apptile.Update(appTileData);
我收到一条错误消息 First()

And I get an error message First()
