后台任务永远不会被触发.获取访问权限后的注册/任务代码：

public sealed class GeofenceTask : IBackgroundTask
{
    public static void Register()
    {
        var taskName = nameof(GeofenceTask);

        foreach (var n in BackgroundTaskRegistration.AllTasks.Where(n => n.Value.Name == taskName))
        {
            n.Value.Unregister(true);
            break;
        }

        var builder = new BackgroundTaskBuilder {Name = taskName,TaskEntryPoint = typeof (GeofenceTask).FullName};
        builder.SetTrigger(new LocationTrigger(LocationTriggerType.Geofence));
        builder.Register();
    }

    public void Run(IBackgroundTaskInstance taskInstance)
    {
        // Do magic.
    }
}

在Windows Phone 8.1设备或模拟器上运行.预更新,它也适用于Windows 10 Mobile.到目前为止有没有已知的解决方案？
