TopNotify is a Windows application that allows users to customize how notifications appear and behave on their desktop. The system consists of a background daemon service that intercepts Windows notifications and modifies their presentation based on user preferences, combined with a system tray-accessible GUI built with React/Vite for configuration. The architecture cleanly separates concerns: the daemon handles notification interception and modification using Windows APIs, while the GUI provides user configuration. Communication between components occurs via mailslots for IPC and a shared JSON settings file. The application employs an interceptor pattern where different aspects of notification handling (positioning, sound, text-to-speech) are implemented as pluggable components. Key technical highlights include native C++ code for enumerating Windows notification windows, sophisticated DPI-aware multi-monitor positioning logic, and a clean plugin architecture for notification interceptors. The application is packaged as an MSIX installer with support for both x64 and ARM64 architectures.
WPFDevelopers is a comprehensive WPF custom control library (NuGet package `WPFDevelopers`) that provides ~50+ themed UI controls, styles, effects, window chrome customization, system tray integration, screen capture, charts, loading indicators, and utility helpers. It also includes a demo application showcasing each control. The library targets a wide range of .NET versions (4.0 through 10.0) and integrates Win32 interop for advanced shell features. While containing some vendored code (Microsoft Expression Blend SDK) and occasional duplication, the library demonstrates solid engineering practices with reusable controls, attached behaviors, and a consistent theming infrastructure. It is actively maintained with CI builds for multiple frameworks.
