Add Powershell 7 to your Powershell ISE

I find this code snippet somewhere on the internet and I like it :)

Just open ISE and paste these code and you are ready to rock!

$ErrorActionPreference= 'silentlycontinue'
$psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Clear()
$psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Add("Switch to PowerShell 7", {
        function New-OutOfProcRunspace {
            param($ProcessId)

            $ConnInfo = New-Object -TypeName System.Management.Automation.Runspaces.NamedPipeConnectionInfo -ArgumentList @($ProcessId)
            $DefaultType = [System.Management.Automation.Runspaces.TypeTable]::LoadDefaultTypeFiles()

            $Runspace = [System.Management.Automation.Runspaces.RunspaceFactory]::CreateRunspace($ConnInfo, $Host, $Default)

            $Runspace.Open()
            $Runspace
        }

        $PowerShell = Start-Process PWSH -ArgumentList @("-NoExit") -PassThru -WindowStyle Hidden
        $Runspace = New-OutOfProcRunspace -ProcessId $PowerShell.Id
        $Host.PushRunspace($Runspace)
}, "ALT+F5") | Out-Null

$psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Add("Switch to PowerShell 5", {
    $Host.PopRunspace()

    $ChildProc = Get-CimInstance -ClassName win32_process | where {$_.ParentProcessId -eq $Pid}
    $ChildProc | ForEach-Object { Stop-Process -Id $_.ProcessId }

}, "ALT+F6") | Out-Null

Happy coding!
