in powershell, set affinity in start-process

Question

In powershell, I can launch a process with

$app_name = "app.exe"
$app_arguments = "arg0"
Start-Process $app_name $app_arguments

I try set the affinity with

$app = Start-Process $app_name $app_arguments
$app.ProcessorAffinity = 0x3

.... no work.

In windows powershell, when I launch a process how I can set the affinity ?

Answer 1

I can solve with

$app_name = "app.exe"
$app_arguments = "arg0"

$pinfo = New-Object System.Diagnostics.ProcessStartInfo
$pinfo.FileName = $app_name
$pinfo.Arguments = $app_arguments
$p = New-Object System.Diagnostics.Process
$p.StartInfo = $pinfo
$p.Start()
$p.ProcessorAffinity=0x3
