in C#/Powershell - Is it possible to change the Idle TimeOut for an IIS Application Pool?

Question

I want to disable the idle timeout (Set it to Zero) of an application pool and I want to perform this at setup time, is it possible to perform this action from C# or PowerShell?

Answer 1

I use the following function to generically grab an app pool object:

$query = "Select * From IIsApplicationPoolSetting WHERE WAMUserName LIKE '%$uServer'"
$query
$pools = Get-WmiObject -Authentication 6 -ComputerName $server -Query $query -Namespace 'root/microsoftiisv2' 
if ($pools)
{
    foreach ($pool in $pools)
    {
        Write-Host("    WAM Pool: " + $pool.Name + ", " + $pool.WAMUserName + " (" + $pool.WAMUserPass + ")")
    }
}

And from an unrelated piece of code, here's where I place a site in a new App Pool. It's just an example how to use Set-WMIInstance.

if ($site.AppPoolID -ne $poolID)
{
    # Write-Host("Updating $($site.Name) from $($site.AppPoolID) to $($poolID)")
    $wmiArgs = @{"AppPoolID"=$poolID}

    [void](Set-WMIInstance -InputObject $site -Arguments $wmiArgs)
} else {
    # Write-Host("No update needed")
}

Use Get-Member to learn what properties your $pool has, then use Set-WMIInstance to modify them.
