Command succeeds in Windows Powershell only

[ahinterl]

(Get-ClusterNetwork -Name '<ClusterNetworkName>').Role = 'None'
succeeds when using Windows PowerShell (check by running (Get-ClusterNetwork -Name '<ClusterNetworkName>').Role.

When using PowerShell 7.5, the Role property is unchanged when checking with (Get-ClusterNetwork -Name '<ClusterNetworkName>').Role.

What's the reason I need to use Windows PowerShell for this command?

The FailoverClustering module is built for Windows PowerShell ( <= 5.1 ) so PowerShell 7.5 has to load it in compatibility mode. (I'm not sure, but I think it's implicitly doing the same thing as the UseWindowsPowerShell parameter for Import-Module.)

If certain commands are still failing, it could be that they have dependencies on types from the .NET Framework that are not included in .NET anymore. Do you get any better clues if you run (Get-ClusterNetwork -Name '<ClusterNetworkName>' -Debug).Role (with the Debug parameter added)?

Understand. Need to make some research on compatibility mode ;-)... Thank you for the explanation.
