AlterNET UI is a cross-platform .NET UI framework that allows the development of light-footprint .NET desktop applications that runs on Windows, macOS, and Linux with Microsoft Visual Studio or Visual Studio Code.
It is built on top of the .NET Framework and uses a XAML-like approach to define user interface and layout. It provides a set of standard controls that looks native on the target OS, such as Text Box, Label, CheckBox, Button, Image, TreeViews, ListView, and more.
The framework includes a platform-independent graphic device interface for rendering graphical objects, such as fonts, brushes, images, and a layout engine.
