Process​

  1. Prompt the user for the package name.
  2. Install Chocolatey if it's not already installed.
  3. Set an alias for the choco binary in PowerShell (due to how VSA passes the commands to the endpoint, and the fact that we can't refresh the session after the first Chocolatey install).
  4. Install NuGet if not already installed.
  5. Install/Update the Foil Module.
  6. Remove the application using Foil-Chocolatey, if the package is installed.
  7. Check to ensure the package was properly removed.
  8. Write the result to the Agent Procedure Log.
