Ejemplo Runspace05

En este ejemplo se muestra cómo agregar un complemento a un objeto System.Management.Automation.Runspaces.InitialSessionState para que el cmdlet del complemento esté disponible cuando se abra el espacio de ejecución. El complemento proporciona un cmdlet Get-Proc (definido por el GetProcessSample01 Sample) que se ejecuta de forma sincrónica mediante un objeto System.Management.Automation.PowerShell.

Requisitos

Este ejemplo requiere Windows PowerShell 2.0.

En este ejemplo se muestra lo siguiente.

Ejemplo

En este ejemplo se crea un espacio de ejecución que usa un objeto System.Management.Automation.Runspaces.InitialSessionState para definir los elementos que están disponibles cuando se abre el espacio de ejecución. En este ejemplo, se agrega un complemento que define un cmdlet Get-Proc al estado de sesión inicial.
