$module = (Get-Module Microsoft.PowerShell.ConsoleGuiTools -Record).ModuleBase
Add-Sort -Path (Be part of-path $module Terminal.Gui.dll)

$outcome = [Terminal.Gui.MessageBox]::Question("Essential", "Do you're keen on PowerShell?", @("Sure", "No"))

# Utilise the results of the choice
# Write output to the terminal window and shut the message field
if ($outcome -eq 0)
{
    # Shutdown the GUI software gracefully
    [Terminal.Gui.Application]::shutdown()
    write-host("It is good you're keen on PowerShell!")

{
    # Shutdown the GUI software gracefully
    [Terminal.Gui.Application]::shutdown()
    write-host("Too dangerous, PowerShell is nice. Give it an opportunity.")
