Following his PSN API PHP Wrapper updates and the recent PSN API Python Wrapper, PlayStation 4 developer @Tustin shared a C# library he's been working on called PlayStationSharp for the PlayStation API with other devs and those seeking to learn today. 
According to a recent tweet on his Twitter, to quote: "PlayStationSharp now also has support for changing profile background image and color. I also included some examples in the test app that let's you change both."

And from the README.md: PlayStationSharp
A C# library for the PlayStation API.
Usage
Notice: The PlayStation.TestApp project provides a more real life application of this library. You can use that as a reference if you so choose.
Due to changes to Sony's login system, you can no longer login with a username and password directly. Instead, this library utilizes their own login form and displays that to the user in a new form when called. This is how you can login using this library.

Logging in
Code:
using PlayStationSharp.API;
// Spawns a new Windows form with Sony's login form.
var account = Auth.CreateLogin();
// Will return null if form was closed manually.
if (account == null) return;
// 'account' variable now contains an instance of the user's account.
