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