What are you seeing?

by having the using I get this error

error CS0246: The type or namespace name 'Spectre' could not be found (are you missing a using directive or an assembly reference?)

What is expected?

From the docs
https://cakebuild.net/docs/writing-builds/console-output#advanced-output
I was expecting that the namespace would be available for referencing

Interesting find. Thanks for reporting @pitermarx. It seems for some reason the Spectre.Console assembly is not being referenced in the compiled C# code. Perhaps it's because we use Spectre.Console via DI and there might not be any direct reference to the assembly (needs investigation).

A possible workaround for now is to force the assembly load by loading Spectre.Console as an addin. e.g.

#addin "nuget:?package=Spectre.Console&version=0.36.0"

using Spectre.Console;

var fruit = AnsiConsole.Prompt(
    new TextPrompt<string>("What's your [green]favorite fruit[/]?")
        .InvalidChoiceMessage("[red]That's not a valid fruit[/]")
        .DefaultValue("Orange")
        .AddChoice("Apple")
        .AddChoice("Banana")
        .AddChoice("Orange"));
AnsiConsole.WriteLine($"I agree. {fruit} is tasty!");

N.B.: The version of Spectre.Console should match the version that is used by the Cake runner you're using. For Cake v1.1.0 it's Spectre.Console 0.36.0, for the next release of Cake (v1.2.0) it will likely be 0.38.0 based on what's in develop right now.

As it ships with Cake it's this will work too

#r "Spectre.Console"
using Spectre.Console

AnsiConsole.Render(
    new FigletText("Hello")
        .LeftAligned()
        .Color(Color.Red));
