Use Import-Module with the -UseWindowsPowerShell parameter, and you can import and use the AzureAD module in PowerShell 7.

That works! is it expected that any module that isn't native to PS7 will require this? I was hoping to not have to re-code all existing scripts/processes :(

Until Azure Active Directory product group makes the AzureAD module compatible with PowerShell 7, we need to use the Windows PowerShell Compatibility feature. You can find more details at https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_windows_powershell_compatibility?view=powershell-7

Thanks for the explanation. I was hopeful that the backward compatibility was a little more "automagic" than that, but it's OK until the modules get updated.

Thank you, it worked!

You could instead try to use the az rest invoking the graph api.
Until the time az-cli is in par with the AzureAD powershell module you can instead use the graph api
az login --tenant <tenantname.onmicrosoft.com>
$uri = "https://graph.microsoft.com/v1.0/applications"
$allApplications = az rest `
--method GET `
--uri $uri `
--headers 'Content-Type=application/json' | convertfrom-json
$allApplications.value |% {"{0}-{1}" -f $_.appid, $_.displayname}
I have put some samples using az rest here,
https://github.com/joepaulk/utilities/blob/master/manage-azuread-applicationregistrations.ps1
You may also refer to: https://damienbod.com/2020/06/22/using-azure-cli-to-create-azure-app-registrations/ from where i picked up inspiration
Other reference, how az rest use the accesstokens from az cli can be found here,
