It is very possible that the necessary .NET classes are not part of .NET core in PowerShell 7. I'm assuming if you run the command in Windows PowerShell it works just fine. I may have to refactor the module not to export Show-GUICalendar for PowerShell 7.

[jdhitsolutions]

Looks like a limitation in PowerShell 7. The .NET class works fine in Windows PowerShell.

But is missing in PowerShell 7

[jdhitsolutions]

Because this is a .NET limitation, obviously I can't fix it. I've updated the module and v2.4.0 no longer exports this command in PowerShell 7. That's the best I can do.

[Agazoth]

It is actually the same in Windows Powershell. I included the error from both.

[jdhitsolutions]

I missed that. That shouldn't be the case. I have never had an issue in Windows PowerShell (testing on multiple systems), but I got the same problem on PowerShell 7. Given that .NET Core is a subset of the .NET Framework in Windows PowerShell, this doesn't surprise me.

I can't think why this would fail in Windows PowerShell. Are you running something like a Home or Student edition? Not that it should make a difference. I can't imagine the Danish culture is causing a problem.

Update the module to 2.4.0 and try again in Windows PowerShell. I changed a parameter to use a string instead of the .NET class. Let's see if you get the same error. The command definitely won't run in PowerShell 7.

I can confirm that it works in Windows PowerShell now. Thanks :-)
