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. -

PushSharp
A server-side library for sending Push Notifications to iOS
PushSharp is a server-side library for sending Push Notifications to iOS/OSX (APNS), Android/Chrome (GCM/FCM), Windows/Windows Phone, Amazon (ADM) and Blackberry devices! PushSharp v3.0+ is a complete rewrite of the original library, aimed at taking advantage of things like async/await, HttpClient, and generally a better infrastructure using lessons learned from the old code. PushSharp will now follow semver versioning, so major version numbers will go up as there are any breaking API changes. The API in v3.x+ series is quite different from 2.x. The goal is to simplify things and focus on the core functionality of the library, leaving things like constructing valid payloads up to the developer. For APNS you will also need to occasionally check with the feedback service to see if there are any expired device tokens you should no longer send notifications to. -

SmartContextMenu
SmartContextMenu adds a context menu to all windows in the system.
This program is enhanced version of SmartSystemMenu. I hope it will be more convenient, because it supports all types of windows, including windows without a system menu. It should also be more stable and lightweight, as it does not use hooks in separate dll modules. To use the app, please, run the file SmartContextMenu.exe, move the mouse cursor to the necessary window and use the hotkeys “Ctrl + Right Mouse Button”. All the menu settings and hotkeys can be changed in the settings dialog of the system tray, as well as in the file SmartContextMenu.xml. -
