# .SYNOPSIS 
# Remove unnecessary files before packaging.
# .DESCRIPTION
# This script removes the runtime assemblies because PowerShell already has them, as well as the .deps.json files because they are not needed.
# .EXAMPLE
# .\RemoveRuntimeAssemblies.ps1 -RootPath "C:\repo\azure-powershell\artifacts\Debug\"
# This example removes the runtime assemblies in the Debug folder
# .EXAMPLE
# .\RemoveRuntimeAssemblies.ps1 -RootPath "C:\repo\azure-powershell\artifacts\Debug\" -CodeSign
# This example removes the runtime assemblies and the runtimes folder
# .NOTES
# It's unclear whether removing the runtimes folder is still necessary because the folder doesn't seem to exist in the build process.
