        and net472 for Desktop (Windows PowerShell 5.1). Throws when that build was never staged,
        naming the path it looked for.
    .PARAMETER ModuleRoot
        The module's own folder, the parent of lib.
    .PARAMETER Edition
        The PowerShell edition to resolve for. Defaults to the running edition ($PSEdition).
