Windows Presentation Foundation
Framework for building Windows desktop applications
Windows Presentation Foundation (WPF) is a UI framework for building Windows desktop applications. WPF supports a broad set of application development features, including an application model, resources, controls, graphics, layout, data binding and documents. WPF uses the Extensible Application Markup Language (XAML) to provide a declarative model for application programming. WPF applications are based on a vector graphics architecture. This enables applications to look great on high DPI monitors, as they can be infinitely scaled. WPF also includes a flexible hosting model, which makes it straightforward to host a video in a button, for example. The visual designer provided in Visual Studio makes it easy to build WPF application, with drag-in-drop and/or direct editing of XAML markup. WinForms is another UI framework for building Windows desktop applications that is supported on .NET (6.0.x/5.0.x/3.1.x). WPF and WinForms applications only run on Windows. -

FlaUI
UI automation library for .Net
FlaUI is a .NET library which helps with automated UI testing of Windows applications (Win32, WinForms, WPF, Store Apps,...). It is based on native UI Automation libraries from Microsoft and therefore kind of a wrapper around them. FlaUI wraps almost everything from the UI Automation libraries but also provides the native objects in case someone has a special need that is not covered (yet) by FlaUI. Some ideas are copied from the UIAComWrapper project or TestStack.White but rewritten from scratch to have a clean codebase. To use FlaUI, you need to reference the appropriate assemblies. So you should decide, if you want to use UIA2 or UIA3 and install the appropriate library from NuGet. You can of course always download the source and compile it yourself. The entry point is usually an application or the desktop so you get an automation element (like a the main window of the application). On this, you can then search sub-elements and interact with them. -

Ooui Web Framework
UI library that brings the simplicity of native UI development to web
Ooui (pronounced weee!) is a small cross-platform UI library for .NET that uses web technologies. It presents a classic object-oriented UI API that controls a dumb browser. With Ooui, you get the full power of your favorite .NET programming language plus the ability to interact with your app using any device. Make sure to add a reference to Ooui before you start running! With just code, a web server that serves the HTML and web socket logic necessary for an interactive button will start. Ooui has been broken up into several packages to increase the variety of ways that it can be used. When the user requests a page, the page will connect to the server using a web socket. This socket is used to keep the server's in-memory model of the UI (the one you work with as a programmer) in sync with the actual UI shown to the user in their browser. This is done using a simple messaging protocol with JSON packets. -
