Is there an open Windows Phone 8.1 application that receives data from the site?

Question

open source

Is there any open source project that could be used as a sample application for Windows Phone 8.1. Perhaps there is material on the Internet, which describes in detail how you can receive and send data to the site (the information on metanit.com/sharp/windowsphone is not enough).

Answer 1

open ? Freudian slip)
Haven't you seen open source applications? Try downloading and building the Chromium sources, and you will understand that if the application is simple (and not like Chromium), then it is easier and easier to write it yourself than to dig into the sources, which is usually almost reverse engineering in complexity.
And avoiding learning HTTP is, among other things, also very stupid.
On freelance, for creating an HTTP client (bot) for someone else's site, they ask for five-figure sums.
And in general, now Web 1.0 has not been around for a long time, and a variety of HTTP requests in one form or another are needed in almost any large project, especially when it comes to the web.
And keep in mind that there are things in the world that are a hundred times more difficult than HTTP, so if you can’t even master HTTP, then what will it be in many other cases?
First, master HTTP in the browser (AJAX), here is a guide to get started:

After that, implement the same from the side of the desktop/mobile application, it doesn't matter under which platform, it will be much easier. The general logic is the same everywhere, because The protocol is the same - HTTP.
