How to PSSession VM from Resource Manager?

I have VMs in Resource Manager and I want to do remote PowerShell scripting from runbook these VMs. I already know how to do it in classic virtual machines and use with success.

Now, is remote PowerShell over SSL with a certificate enabled by default on Azure VMs created with the Azure Resource Manager? How do I connect with Enter-PSSession or Invoke-Command?

I tried this code without success.

Enter-PSSession -ComputerName <public-IP> -Credential $cred -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck -SkipRevocationCheck)

And I got this error

Enter-PSSession : Connecting to remote server <public-IP> failed with the following error message : The WinRM client 
cannot process the request. If the authentication scheme is different from Kerberos, or if the client computer is not 
joined to a domain, then HTTPS transport must be used or the destination machine must be added to the TrustedHosts 
configuration setting. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts list might not 
be authenticated. You can get more information about that by running the following command: winrm help config. For more 
information, see the about_Remote_Troubleshooting Help topic.

Note: That I am running this with Powershell Runbook in Azure Automation. and tried the suggested answer here

You need to put a cert in Azure Key Vault (plus some other steps) to enable WinRM to ARM VMs. Then you need to do the same thing as in the Connect-AzureVM runbook, but using this cert instead of the Azure Classic VM's cert, to set up trust between the hosts.

See this thread for more details on the steps required. This may be useful as well.
