Hi @xumou-ms did you met any problem in Windows PowerShell or PowerShell below 7.0? Could you submit an issue if you did? Because we are still supporting those platforms.

@hvermis could you help review the help doc of New-AzDataFactoryV2LinkedServiceEncryptedCredential?
Thanks

Hello @isra-fel. To meet Azure compliance requirements, we need to remove SSL self-signed cert from Self-Hosted IR. Which causes the underlying implementation isn't supported by .NET Standard 2.0. But .NET Core 3.1 can support that. So, PowerShell 7 is necessary.

Got it. I suppose it would be even better if we could do the check in code as well, so the cmdlet can fail fast.

BTW you could use the snippet $PSVersionTable.PSVersion -lt "7.0.0" to tell the version.
