Примеры кода RunSpace05

Ниже приведен исходный код для примера Runspace05, описанного в разделе "Настройка пространства запуска с помощью RunspaceConfiguration". В этом примере показано, как создать сведения о конфигурации пространства выполнения, создать пространство выполнения, создать конвейер с одной командой, а затем выполнить конвейер. Команда, которая выполняется, является командлетом Get-Process.
