Windows Phone App with 4SQ

C#

I'm want to create my own Coffee shop app for this semester's project. It's a Windows Phone App.

The App can view who is checked-in, view menus, view photos by using 4SQ Endpoint APIs.

My problem is I don't know how to start it... which book I should read about C#? And I don't know which keywords should I google? i.e. GET POST METHOD , JSON

I have used 4SQ Endpoint APIs once with javascript (jquery) $.ajax{(.....)} to get data from 4SQ Endpoint APIs. I googled and found JSON.NET Class but I don't know how to use it because I have never programmed in C#.

I'm just beginning programming and I can programming in C only.
