Get user Name and Photograph from Twitter in Windows 8 App

Question

Hi,

I have a Windows 8 App , which calls to Twitter via Azure Mobile Service. Intially I was able to get the user's json information ( Name and Profile picture ) by passsing the ID to 

https://api.twitter.com/users/<Twitter_ID>

However with the change of twitter API 1.1 this doesnot work.

Please help me getting the correct signature format.
