Можете ли вы запустить Microsoft.VisualStudio.SlowCheetah из PowerShell?

Итак, вот мое доказательство концепции:

Моя папка содержит 4 файла:

1. PerformTransform.ps1 — замена моего скрипта сборки, который инициирует преобразование.
2. Transform-Config.ps1 — скрипты, использующие SlowCheetah для выполнения преобразований.
3. Sample.config — пример файла конфигурации
4. Sample.Prod.config — пример файла преобразования XML.

PerformTransform.ps1 выглядит так:

cls
$scriptPath = split-path -parent $MyInvocation.MyCommand.Definition

# Temporarily adds the script folder to the path
# so that the Transform-Config command is available
if(($env:Path -split ';') -notcontains $scriptPath) {
    $env:Path += ';' + $scriptPath
}

Transform-Config "$scriptPath\Sample.config" "$scriptPath\Sample.Prod.config" "$scriptPath\Sample.Transformed.config"

Вот мой Transform-Config.ps1:

#!/usr/bin/env powershell

.SYNOPSIS
    You can use this script to easly transform any XML file using XDT or JSON file using JDT.
    To use this script you can just save it locally and execute it. The script
    will download its dependencies automatically.

Файлы конфигурации не важны, вы должны иметь возможность использовать существующие файлы преобразования app.config и app.ENV.config, чтобы поиграть с этим.

Если есть более простой способ сделать это, пожалуйста, дайте мне знать!
