There are several demo’s online that connect a Windows Store App to Facebook, Twitter, etc. using OAuth 1.x and OAuth 2.0. Although these demo’s show how this works, the code is hard to reuse across applications, because it is tightly coupled to the main app page. I’ve completely rewritten the code to make the code reusable, and to make the OAuth 1.x and OAuth 2.0 interface almost identical, so you can use a single codebase to connect with both protocols. You can download the OAuth demo (71 KB), which includes an OAuth 1.x library you can use in the same manner as with OAuth 2.0.
The book is written in tutorial style, encouraging to learn by working along with the author. This is backed up by detailed explanation of what’s going on and why this is important. The book covers a lot of ground, from the anatomy of an application to using device capabilities, audio & video playback etc. I personally don’t like the “trying to be funny” writing style of the author, but it wasn’t too annoying considering the wealth of information and good explanations.
