ControlChannelTrigger in UWP Windows 10 access denied

问题

I am trying to implement background task with ControlChannelTrigger using WebSockets. In MSDN example I get an exception while running on Windows 10 Desktop in this place:

channel = new ControlChannelTrigger(channelId, serverKeepAliveInterval,ControlChannelTriggerResourceType)

Exception is "Access denied"

However in Windows 10 mobile this line passes and I get an exception Access Denied in the last line of the following block:

channel.UsingTransport(socket);   
var uri = new Uri(url);          
await socket.ConnectAsync(uri);

Is there any solution?
