Windows Universal App (8.1) failed to call subscribeToPushService()

[vwong53]

My application get hanged when it reaches this function subscribeToPushService(). When i disable it, the application runs smoothly. But i cannot retrieve the pushToken value.

I did it include the PushSDK reference and also adding the c# PushSDK project into my application.
The platform i'm working on is windows 8.1 universal app.

Please kindly advice how should i do to get the push notification work on this window platform.
Thanks
