There has been a big change to the Spectre.Cli project that I’m using in the CLI Lesson series. The project and package has moved into the Spectre.Console project. This combines the code for building command-line interface apps with the Spectre.Console capabilities to create rich, modern console UI with color, layout, and controls.
While this is a good change to bring together these libraries and support, it is disruptive to existing projects. Here is a migration guide for moving your project from the Spectre.Cli to Spectre.Console package (available with Spectre.Console version 0.36.
I will update the current Cli Lesson projects and articles to use the new package over the next week or so to align with the new direction.
