A PowerShell Core function designed to send output to an instance of Out-Gridview in Windows PowerShell. This requires you to be running a full graphical desktop like Windows 10.

#requires -version 6.1

Function Send-ToPSGridView {

<#
.SYNOPSIS
Send objects to Out-Gridview in Windows PowerShell
.DESCRIPTION
This command is intended as a workaround for PowerShell Core running on a Windows platform, presumably Windows 10. PowerShell Core does not support all of the .NET Framework which means some commands like Out-Gridview are not supported. However, on a Windows desktop you are most likely running Windows PowerShell side by side with PowerShell Core. This command is designed to take objects from a PowerShell expression and send it to an instance of Windows PowerShell running Out-Gridview. You can specify a title and pass objects back to your PowerShell Core session. Note that passed objects will be deserialized versions of the original objects.
.PARAMETER Title
Specify a Title for the Out-Gridview window
.PARAMETER Passthru
Pass selected objects from Out-Gridview back to your PowerShell Core session.
.EXAMPLE
PS C:\> get-childitem c:\scripts\*.ps1 | Send-ToPSGridview -title "My Scripts"
Press Enter to continue...:

Display all ps1 files in Out-Gridview. You must press Enter to continue.
.EXAMPLE
PS C:\>  get-service | where status -eq 'running' | Send-ToPSGridView -Passthru | Restart-service -PassThru
Press Enter to continue...:

Status   Name               DisplayName
------   ----               -----------
Running  BluetoothUserSe... Bluetooth User Support Service_17b710
Running  Audiosrv           Windows Audio

Get all running services and pipe to Out-Gridview where you can select services which will be restarted.
.EXAMPLE
PS C:\> $val = 1..10 | Send-ToPSGridView -Title "Select some numbers" -Passthru
Press Enter to continue...:
PS C:\> $val
4
8
6
PS C:\> $val | Measure-Object -sum

Maximum           :
Minimum           :
StandardDeviation :
Property          :

Send the numbers 1 to 10 to Out-Gridview where you can select a few. The results are saved to a variable in the PowerShell Core session where you can use them.
