@aollivierre Please move the issue to Azure feedback site.
Perhaps it is here https://feedback.azure.com/forums/169401-azure-active-directory

@toddwseattle We need a simply repo to discover a root of the issue. Azure site is good place to start.

I'm logging in with my Office365 admin / AzureAD address that has 2 factor auth. The popup comes up; i enter the password and text code; and then I get the errors.
What else do you need?

I was having issues connecting to the SFB module as well when using the v7 but was unable to connect properly. After switching my VS Code's shell to the regular 5.1 I was able to login properly to that service.

Exactly the same behaviours as @O365scripts

Noted this to when attempting to connect to O365. Posted a question to https://docs.microsoft.com/en-us/office365/enterprise/powershell/connect-to-office-365-powershell#connect-with-the-microsoft-azure-active-directory-module-for-windows-powershell, and the related GitHub, but as noted in that issue, is looks like PS Core is not support for AzureAD or the Msol named CmdLets.
I guess there is not much that can by done until Azure Az catches up.
Summary: Connect to your Office 365 organization using Office 365 PowerShell to perform admin center tasks from the command line.

Sorry, Screen shot is not allowed to attach. Add attachment here should be a cool feature.
The PowerShell is version 7.

In short, it's not supported in .NET Core, and therefore not in PowerShell Core (7.X).

@ohadschn I tried your steps but issue is still not resolved. My machine is Windows 10. t already had Powershell 5.1. But today I installed Core based 7.x latest release of Powershell. I am using 7.x ISE of PS to run AZ module command and so it asked for Azure login and faced same error.

Hi, @hmahajanHM
Try this
Install-Module Microsoft.Graph
Connect-Graph
Get-MgUser | select -First 5
It works in my PS7.0 There is no instruction how to create a new user, but getting existing is fine.

@hmahajanHM most likely you already had incorrect PS assemblies loaded onto the ISE process. I suggest you start a new regular PowerShell terminal process (Start Menu -> PowerShell) and try again.

Hi, I am having the same issue and I am installing on 64-bit.Did you find the solution?

As posted above I have the same thing happening. 7.0 power-shell core causes the same error to take place.
Using power-shell 5.1 things seem to work just fine.

Same as what JeretSB said. 7.0.2. fails. 5.1 works.

Use: Import-Module AzureAD -UseWindowsPowerShell
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

@SteveL-MSFT is there a place the AzureAD team has a uservoice or something so we can ask them for the code change described in https://github.com/dotnet/runtime/issues/25044?

@JustinGrote couldn't find one I would suggest starting in Azure PowerShell repo and maybe they can help redirect

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,
