Powershell start-process Runspace wont start except with -noexit flag

Question

So i wrote this little GUI with Runspaces. it works as expected when running it in ISE, and if i start it from a PS prompt, but when i try to run it from a Shortcut it just wont boot as long as i dont use the -noexit flag. but when using the -noexit flag it will leave the Powershell process running even after i close the GUI.

iam using this tecnuiqe for my GUI: Powershell GUI Template

this is what i have in my shortcut: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -sta -WindowStyle Hidden -file "C:\Temp\Runspaceversion.ps1"

that wont work... but if i do

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -sta -WindowStyle Hidden -noexit -file "C:\IT\Checklist\Runspaceversion.ps1"

it works, but i get the powershell process idling when i exit the Gui....

PS can be picky about its own command line arguments, post what you've got in the shortcut with and without so we can advise. — Deadly-Bagel

There is no exit code in the template being used.

When the Window is closed, this fires...

    #region Window Close 
    $syncHash.Window.Add_Closed({
        Write-Verbose 'Halt runspace cleanup job processing'
        $jobCleanup.Flag = $False

        #Stop all runspaces
        $jobCleanup.PowerShell.Dispose()

    })

Change that block to include something like this...

    #region Window Close 
    $syncHash.Window.Add_Closed({
        Write-Verbose 'Halt runspace cleanup job processing'
        $jobCleanup.Flag = $False

        #Stop all runspaces
        $jobCleanup.PowerShell.Dispose()
        $jobProcessInfo = (Get-WmiObject win32_process `
        -Filter {name = 'powershell.exe' and commandline like '%PowerShell_GUI_Template.ps1%'})
        Stop-Process -Id $jobProcessInfo.ProcessId

    })

Of course this may be a brute force way of doing this, but I pulled down the template and this works for closing the associated host process on the closing the form Window.

This is what I have in the shortcut.

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noprofile -noexit "& { D:\Scripts\PowerShellTips\PowerShell_GUI_Template.ps1 }
