Powershell 7+ Cannot Administer IIS 10 with the IISAdministration Module

The following code will work (only sometimes though ??) with older versions of PowerShell but not at all with version 7+.

All I want to do is create a new Application Pool in IIS 10+.

The documentation is very poor and most examples don't work anymore. Is there something I am missing here?

   # PowerShell 7.2.6

   # Windows Server 2019 (With the GUI).

   # IIS 10 etc is already installed.

   # Executed as Administrator.

   # NOTE: This imports the IISAdministration module not the old WebAdministration module.
   Import-Module -Name IISAdministration -UseWindowsPowerShell -WarningAction SilentlyContinue

   Reset-IISServerManager -Confirm:$false

   Start-IISCommitDelay

   # Create the foo.co.uk application pool.

   Write-Host "Creating the foo.co.uk application pool.`n" -ForegroundColor Green

   $ServerManager = Get-IISServerManager
   $ServerManager.ApplicationPools.Add("foo.co.uk.apppool")

   # $ServerManager.CommitChanges() (this doesn't work though I keep seeing it in examples.)

   Stop-IISCommitDelay

I have now tried many examples of code that are similar to the above from the few online examples I can find and none of them work.

Solution

  • I am not real sure why you are encountering this (and not in any position to experiment), but, when push comes to shove, you can always call ...

    appcmd add apppool /name:myAppPool

    or with other settings

    appcmd add apppool /name:myAppPool /managedRuntimeVersion:v2.0 /managedPipelineMode:Integrated
appcmd add apppool /name:myAppPool /managedRuntimeVersion:v2.0 /managedPipelineMode:Classic

    ... directly from your script, regardless of the Powershell version, but I get you are trying to stay in pure PowerShell.
