Out-GridView failing, when run from within packaged EXE Form application

PowerShell Tools PowerShell Pro Tools Help

I have a forms application which runs OK in VSCode and PowerShell_ISE

When packaged with
PowerShellCore = $true
DotNetVersion = ‘netcoreapp31’
PowerShellVersion = ‘7.0.0’

Forms display OK, calls a function which has File Browser/Picker, Out-GridView works OK.

However, when packaged, the above all work but Out-GridView throws this error

Attempt by method ‘Microsoft.Management.UI.Internal.InnerListColumn…ctor(Microsoft.Management.UI.Internal.UIPropertyGroupDescription, Boolean, Boolean)’ to access method ‘System.Management.Automation.Internal.GraphicalHostReflectionWrapper.EscapeBinding(System.String)’ failed.

The Grid-View window shows, but just has blank with spinning circle.

I have in the code:
Add-Type -AssemblyName System.Windows.Forms -Verbose

I tried with/without the following:
Add-Type -AssemblyName System.Management.Automation -Verbose

Any clues/tips for resolution, understanding if there are missing dependences, gratefully accepted?

I’ll have to take a look at this. I haven’t tried to use Out-GridView in a package v7 exe so there might be something missing that we need to include but I’m not sure what it is.

I’m getting this issue now too with the latest version. Was this found and solved (and reappeared later on), or was the root cause never found?
