Create VM with static DIP and reserved IP

I want to create the new VM so that it has fix DIP from my subnet and virtual network and associated cloud service should have reserved iP.

tried following script

Import-AzurePublishSettingsFile -PublishSettingsFile my.publishsettings

Set-AzureSubscription -SubscriptionName "ICM-Genpact US" -SubscriptionId "548****..." -CurrentStorageAccountName "iconunigenstorage"

Select-AzureSubscription -SubscriptionName "ICM-Genpact US" 


$ImageName = (Get-AzureVMImage | 
                Where { $_.ImageFamily -eq "Windows Server 2012 R2 Datacenter" } | 
                sort PublishedDate -Descending | Select-Object -First 1).ImageName




    $ReservedIP = Get-AzureReservedIP -ReservedIPName "GenpactUnigenVM"

New-AzureVMConfig -Name "iconunigen" -InstanceSize "Small" -ImageName $ImageName | 
  Add-AzureProvisioningConfig -Windows -AdminUsername icertisadmin -Password Password#123 |
  Set-AzureSubnet -SubnetNames "UnigenVMLayer" |
  Set-AzureStaticVNetIP -IPAddress 192.168.2.44 |
  New-AzureVM -ServiceName "iconunigen" –ReservedIPName $ReservedIP -Location "genpactdallasnw" 

but failing with errors

New-AzureVM : BadRequest: The location constraint is not valid
