Old working script in powershell doesnt work after upgrade to powershell-core (v 7.2) and remove previous one

Question

This is a script to automatically turn on mobile hotspot if its not (from this answer)

$asTaskGeneric = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and $_.GetParameters()[0].ParameterType.Name -eq 'IAsyncOperation`1' })[0]
$asTaskGeneric = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and $_.GetParameters()[0].ParameterType.Name -eq 'IAsyncOperation`1' })[0]
Function Await($WinRtTask, $ResultType) {
    $asTask = $asTaskGeneric.MakeGenericMethod($ResultType)
    $netTask = $asTask.Invoke($null, @($WinRtTask))
    $netTask.Wait(-1) | Out-Null
    $netTask.Result
}
Function AwaitAction($WinRtAction) {
    $asTask = ([System.WindowsRuntimeSystemExtensions].GetMethods() | ? { $_.Name -eq 'AsTask' -and $_.GetParameters().Count -eq 1 -and !$_.IsGenericMethod })[0]
    $netTask = $asTask.Invoke($null, @($WinRtAction))
    $netTask.Wait(-1) | Out-Null
}

$connectionProfile = [Windows.Networking.Connectivity.NetworkInformation, Windows.Networking.Connectivity, ContentType = WindowsRuntime]::GetInternetConnectionProfile()
$tetheringManager = [Windows.Networking.NetworkOperators.NetworkOperatorTetheringManager, Windows.Networking.NetworkOperators, ContentType = WindowsRuntime]::CreateFromConnectionProfile($connectionProfile)
if ($tetheringManager.TetheringOperationalState -eq 1) {
    "Hotspot is already On!"
}
else {
    "Hotspot is off! Turning it on"
    Await ($tetheringManager.StartTetheringAsync()) ([Windows.Networking.NetworkOperators.NetworkOperatorTetheringOperationResult])
}

now after upgrading powershell to version 7.2 and removing previous one it doesnt work by throwing these errors:

If installing the previous one is not an option, any new updates for this script working in powershell-core?

Answer 1

That is due to running code built for .NET Framework 4.x with powershell 6.x or 7.0.

Wrap your script with the following and it should work.

$session = New-PSSession -UseWindowsPowerShell
Invoke-Command -Session $session {
    enter code here
}
