RDP Connect to an Azure VM from PowerShell

Not a biggie. I was bored of downloading the RDP file for my Azure VMs from the portal or going to where I downloaded them and launching from there, so I created a PowerShell function to launch RDP with my VM details directly from the command-line. 

Like I said, not a biggie. Add the above to your $PROFILE and then you can connect to VMs by typing ConnectRDP-AzureVM 'vmname'. It launches full-screen but you can change that in the function above. 

Update: Use the one below. While the above snippet is fine, it uses the VM IP address and when you have many sessions open it quickly becomes confusing. 

Reason I used IP address was because the Get-AzureVM output gives the DNSName as http://<somename>.cloudapp.net/ and I didn’t want to fiddle with extracting the name from this URL. Since I want to extract the hostname now here’s what I was going to do:

First line does a regex match on the DNSName attribute. Second line extracts the hostname from the match. It’s fine and does the job, but feels unelegant. Then I discovered the System.URI class. 

So now I do the following:

Get it? I cast the URL returned by $VM.DNSName to the System.URI class. This gives me attributes I can work with, one of which is Host which gives the hostname directly. Here’s the final snippet:

Update2: Turns out there’s a cmdlet that already does the above! *smacks forehead* Didn’t find it when I searched for it but now stumbled upon it by accident. Forget my snippet, simply do:

Replace -Launch with -LocalPath \absolute\path\to\file.rdp if you’d just like to save the config file instead of launching.

Update 3: In case you are using the snippet above, after deploying a VM via PowerShell I realized the Remote Desktop end point is called differently there. Eugh! Modified the code accordingly:
