$RunspacePool = [runspacefactory]::CreateRunspacePool(1, $MaxThreads, $ISS, $Host)
$RunspacePool.Open()

$Code = [ScriptBlock]::Create($(Get-Content $FileName))
$PowershellThread = [powershell]::Create().AddScript($Code)

$PowershellThread.RunspacePool = $RunspacePool
$Handle = $PowershellThread.BeginInvoke()

$Job.Handle = $Handle
$Job.Thread = $PowershellThread
$Job.Object = $Object.ToString()

$Job.Thread.EndInvoke($Job.Handle)
$Job.Thread.Dispose()
