PowerShell Direct + Hot Add NIC == Give me an IP address

Here is a fun script snippet that is possible with Windows 10:

functionaddNicWithIP([string]$VMName,$cred,[string]$Switch,[string]$IPaddress,[string]$subnetPrefixLength){
   $newNetAdapter=Add-VMNetworkAdapter-VMName$VMName-SwitchName$Switch-Passthru
   Write-Output"[$($VMName)]:: Wait for IP address and create virtual switch"
   waitForPSDirect$VMName$cred
   icm-VMName$VMName-Credential$cred {
      param($IPAddress,$subnetPrefixLength,$MacAddress)
      # Wait for the NIC to appear
      do {sleep1} until (@(get-netadapter|?PermanentAddress-eq$MacAddress).Count -eq1)
      # Setup IP Address
      New-NetIPAddress-IPAddress$IPAddress `
                       -InterfaceAlias (get-netadapter|?PermanentAddress-eq$MacAddress).Name `
                       -PrefixLength$subnetPrefixLength
      }-ArgumentList$IPAddress,$subnetPrefixLength,$newNetAdapter.MacAddress
}

What this does is:

1. Adds a new network adapter to a running virtual machine
2. Finds the new network adapter inside the virtual machine
3. Assigns a static IP address to the new network adapter

You can call it like this:

addNicWithIP-VMName"PowerShell Container"-cred$localCred-Switch"Virtual Switch"-IPaddress"192.168.10.10"-subnetPrefixLength"24"
