Gist an Inactive Tcp Port finder in PowerShell

Get-InactiveTcpPort.ps1

function Get-InactiveTcpPort {
    $listener = [System.Net.Sockets.TcpListener]::new(0)
    $listener.Start()
    [int]$port = $listener.LocalEndpoint.Port
    $listener.Stop()
    return $port
}

# faster version
function Get-InactiveTcpPort {
    Begin {
        $listener = [System.Net.Sockets.TcpListener]::new(0)
        $listener.Start()
    }
    Process {
        [int]$port = $listener.LocalEndpoint.Port
        Write-Output $port
    }
    End {
        $listener.Stop()
    }
}

Was inspired to make a small port finder on reading this Gist from the Master StartAutomating Gist a small event-based HTTP server in PowerShell
