Runspace05-codevoorbeeld

Hier is de broncode voor het Runspace05-voorbeeld dat wordt beschreven in Een runspace configureren met RunspaceConfiguration. In dit voorbeeld ziet u hoe u de configuratiegegevens van de runspace maakt, een runspace maakt, een pijplijn maakt met één opdracht en vervolgens de pijplijn uitvoert. De opdracht die wordt uitgevoerd, is de Get-Process cmdlet .
