Terminal.Gui
Console-based user interface toolkit for .NET applications
...Terminal drivers for Curses, Windows Console, and the .NET Console mean Terminal.Gui works well on both color and monochrome terminals and has mouse support on terminal emulators that support it. Both keyboard and mouse input are supported, including limited support for drag & drop. Terminal.Gui supports both Absolute layout and an innovative UI layout system referred to as Computed Layout.
