Exploring and Building Cross-Platform TUIs
summary
Demos use terminal.gui on .NET Core and the Microsoft Console GUI Tools module to build cross‑platform TUIs: Out-ConsoleGridView for in‑terminal grids, PSReadLine history bound to F7, PSEdit (an embedded editor), file dialogs and dynamic tree views. Code patterns include Application.New and the required Application.Shutdown, mainloop invocation for thread safety, and casting dialog.filepath.tostring because it returns an insstack.ustring. Many dozens of views exist, async background jobs sometimes behave oddly, and most examples run successfully.
