Top 5: Best Open Source HTML Rendering library to use HTML5/CSS3 as user interface in C#

Desktop applications used to have normally the same UI kit as the operative system, specially those created with the .NET framework. Other languages, like Java implement other UI kits that look different, but not better. That's why in the last couple of years, a new tendence appeared, the possibility of creating user interfaces with easily writable and customizable components that look exactly how you want as long as you can design it, without depending of the UI kit of your framework or operative systems.

In this top, we want to share with you 5 of the most useful rendering engine/libraries that you can use to create user interfaces for desktop with web technologies.
