The term 'New-AzureRmUserAssignedIdentity' is not recognized as the name - powershell

Question

I'm trying to create user assigned identity, the documentation says that 6.13 should include this function: https://learn.microsoft.com/en-us/powershell/module/azurerm.managedserviceidentity/new-azurermuserassignedidentity?view=azurermps-6.13.0
I uninstalled old versions of Azure RM and installed the latest:
PS C:\Users\user> Get-Module AzureRM -ListAvailable | Select-Object -Property Name,Version,Path
Name Version Path
---- ------- ----
AzureRM 6.13.1 C:\Program Files\WindowsPowerShell\Modules\AzureRM\6.13.1\AzureRM.psd1
But when I try to use it I get the following error:
PS C:\Users\zakima> New-AzureRmUserAssignedIdentity -ResourceGroupName PSRG -Name ID1
New-AzureRmUserAssignedIdentity : The term 'New-AzureRmUserAssignedIdentity' is not recognized as the name of a
cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify
that the path is correct and try again.

+ New-AzureRmUserAssignedIdentity -ResourceGroupName PSRG -Name ID1
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (New-AzureRmUserAssignedIdentity:String) [], CommandNotFoundException

Am I missing some config setting?

Answer 1

The New-AzureRmUserAssignedIdentity Cmdlet resides in the AzureRM.ManagedServiceIdentity module. This module in turn can be found in the PowerShell Gallery and can be installed via:
Install-Module -Name "AzureRM.ManagedServiceIdentity" -AllowPrerelease
Note that the AllowPrerelease flag for Install-Module might not be available for your installed PowerShellGet version, so you might need to update it before the above would work:
Install-Module "PowerShellGet" –Repository "PSGallery" –Force

Answer 2

The problem is that UserAssignedIdentity is still in preview and apparently is not included in AzureRM package.
The following steps made it work for me:
Move to Az package (note - you need uninstall AzureRM first!). It still doesn't include New-AzUserAssignedIdentity.
Install Az.ManagedServiceIdentity directly by running this command:
Install-Module -Name Az.ManagedServiceIdentity
Enjoy!
