Powershell: Get-WinUserLanguageList cmdlet fails

[anthony-geoghegan]

Now that I’m using a Windows 10 laptop for working from home, I decided to try using PowerShell Core and discovered the following error when attempting to run the Get-WinUserLanguageList cmdlet. I’m not a programmer (mostly a GNU/Linux sysadmin) and I was never particularly proficient at PowerShell but this looks like C#/.NET error.

The Get-WinUserLanguageList cmdlet is provided by the International module which is listed as being compatible with Core, Desktop. The cmdlet works in Windows PowerShell 5.1 and not in PowerShell Core 7.1 so I hope I’m reporting this bug to the right place. If not, let me know where I should report this and if so, I hope I've provided enough relevant information.

Steps to reproduce

Invoke the following cmdlet:

Get-WinUserLanguageList

Expected behaviour

Windows PowerShell 5.1 on the same machine returns details of the language list for the current user account:

> Get-WinUserLanguageList -Verbose

LanguageTag     : en-IE
Autonym         : English (Ireland)
EnglishName     : English
LocalizedName   : English (Ireland)
ScriptName      : Latin
InputMethodTips : {1809:00000809, 1809:00001809}
Spellchecking   : True
Handwriting     : False

Actual behaviour

> Get-WinUserLanguageList -Debug
Get-WinUserLanguageList: Cannot marshal 'parameter #2': Invalid managed/unmanaged type combination.

You can import Windows PowerShell module in WindowsPowerShell mode which is available as a parameter for Import-Module cmdlet.

Import-Module -Name International -UseWindowsPowerShell -Verbose

@anthony-geoghegan The module is not in the repository. We could use Windows Feedback tool to report the issue.

/cc @anmenaga for information.

WHY doesn't PowerShell 7.1 recognise this module as not working natively? While I get that the team behind the module hasn't bothered to port to 7.x, shouldn't PowerShell force this module to use the compatibility solution.

It feels like compatibility is not a top issue going forward.

I really don't understand....sorry...i just would like to get twrp to my mate 10 pro (bla-l29). I don't know how this TomTom get here

[anthony-geoghegan]

Thanks, @kvprasoon I wasn't aware of the -UseWindowsPowerShell option or Windows PowerShell Compatibility

@iSazonov I’ve used the Feedback Hub (that comes with Windows 10) to report this problem, under the Input and Language category, including a link to this GitHub issue.
