WNS notfify multiple clients
===

I’m developing a WCF Service for Tile notifications for a winrt application. 

Now I’m now using a foreach to send the notification true WNS to the registered clients.
This foreach I can update by using a different thread to perform the requests.

The questing I have: 
Isn’t there a way to create a batch and then send 1 request to WNS to notify all registered clients
Or is there a better practice?
