Azure DNS: testing CNAME with NSLOOKUP does not show expected result

Hi there,

i'm trying to create a CNAME record, and then test it with NSLOOKUP, but the result is not what i expected:

1. i create an A record for a domain:

$rs = New-AzureDnsRecordSet -Name "@" -RecordType "A" -ZoneName "contoso.com" -ResourceGroupName "MyAzureResourceGroup" -Ttl 60
Add-AzureDnsRecordConfig -RecordSet $rs -Ipv4Address 1.2.3.4
Set-AzureDnsRecordSet -RecordSet $rs

2. i create an CNAME record pointing to the A record of the domain domain:

$rs = New-AzureDnsRecordSet -Name "www" -RecordType "CNAME" -ZoneName "contoso.com" -ResourceGroupName "MyAzureResourceGroup" -Ttl 60
Add-AzureDnsRecordConfig -RecordSet $rs -Cname "contoso.com"
Set-AzureDnsRecordSet -RecordSet $rs

3. i test the resolving with NSLOOKUP

• the A record resolves as expected
  
  

> nslookup contoso.com ns1-09.azure-dns.com
Server: Unknown
Address: 208.76.47.9
Name: contoso.com
Address: 1.2.3.4

• the CNAME record shows no adress and alias
  
  

> nslookup www.contoso.com ns1-09.azure-dns.com
Server: Unknown
Address: 208.76.47.9
Name: www.contoso.com

• my expected result would look like this
  
  

> nslookup www.contoso.com ns1-09.azure-dns.com
Server: Unknown
Address: 208.76.47.9
Name: contoso.com
Address: 1.2.3.4
Aliases: www.contoso.com
