SharpConsoleUI terminal application framework

managedcode/sharpconsoleui

Source managedcode/dotnet-skills ↗License MIT

Use SharpConsoleUI to build full terminal (TUI) applications in .NET — equally suited to full-screen single-window apps and multi-window desktops with overlapping draggable windows — using a compositor, a DOM layout engine, and 40+ reactive controls (data tables, tree views, forms, an embedded PTY terminal, markdown, charts, video). USE FOR: interactive console apps, full-screen TUIs, multi-window terminal desktops, dashboards, wizards, and admin/monitoring UIs that need focus, mouse, and flicke

SharpConsoleUI terminal application framework

Trigger On

building an interactive terminal UI: dashboards, wizards, settings screens, admin/monitoring consoles
building a full-screen single-window TUI: a .Frameless() (no title bar, no title buttons) + .Maximized() app that owns the whole terminal
building a multi-window terminal desktop: overlapping windows with drag/resize/minimize/maximize, z-order, focus routing, modal windows, and mouse support (full-screen and multi-window are equally first-class here)
wanting flicker-free rendering that stays clean over SSH (diff-based cell buffer, not full repaints)
needing rich terminal controls: data tables, tree/list views, forms, an embedded PTY terminal, markdown, charts, or video
shipping a NativeAOT-ready console application with a real UI

Do not trigger for plain line-based CLI tools, argument parsing, or non-interactive scripts.
