[nuget] Extracting Nupkg files using command line

Firstly, I do not want to use Visual Studio at all when dealing with the certain .nupkg files.

I know there is a tool called NuGet Package Explorer and this can export nupkg files to a certain file location using a gui, but I'm looking to setup a MSBuild task to run and unpack about 50 .nupkg files, using the command line.

My question is, is there a tool you can use via the command line which will unpack .nupkg files to a specified file location?

NuPKG files are just zip files, so anything that can process a zip file should be able to process a nupkg file, i.e, 7zip.

This worked for me:

Rename-Item -Path A_Package.nupkg -NewName A_Package.zip

Expand-Archive -Path A_Package.zip -DestinationPath C:\Reference

did the same thing like this:

clear
cd PACKAGE_DIRECTORY

function Expand-ZIPFile($file, $destination)
{
    $shell = New-Object -ComObject Shell.Application
    $zip = $shell.NameSpace($file)
    foreach($item in $zip.items())
    {
        $shell.Namespace($destination).copyhere($item)
    }
}

Dir *.nupkg | rename-item -newname {  $_.name  -replace ".nupkg",".zip"  }

Expand-ZIPFile "Package.1.0.0.zip" “DESTINATION_PATH”

With PowerShell 5.1 (PackageManagement module)

Install-Package -Name MyPackage -Source (Get-Location).Path -Destination C:\outputdirectory

Rename it to .zip, then extract it.
