using Terminal.Gui;

using IApplication app = Application.Create ();
app.Init ();

using Wizard wiz = new () { Title = "Setup Wizard" };

// Add first step
WizardStep firstStep = new () { Title = "License Agreement" };
firstStep.NextButtonText = "Accept!";
firstStep.HelpText = "End User License Agreement text.";
wiz.AddStep (firstStep);

// Add second step
WizardStep secondStep = new () { Title = "User Info" };
secondStep.HelpText = "Enter your information.";
TextField name = new () { X = 0, Width = 20 };
secondStep.Add (new Label { Text = "Name:" }, name);
wiz.AddStep (secondStep);

wiz.Accepting += (_, e) =>
{
    MessageBox.Query ("Complete", $"Name: {name.Text}", "Ok");
    e.Handled = true;
};

app.Run (wiz);

Remarks

Each WizardStep can host arbitrary Views and display help text. Navigation buttons (Back/Next/Finish) are automatically managed.

Can be displayed as a modal dialog or embedded view. When modal, completing the wizard raises Accepting and sets Result.
