Simple Powershell with Vs2019 radio buttons question

Boyd Mills 21

I try a simple example from

https://learn-powershell.net/2014/08/10/powershell-and-wpf-radio-button/

Please advise as to what went wrong.

Since the example is older than vs2019, that shouldn't be the issue.

I have PowerShell extensions installed.
