I created a Windows 8.1 VM on Azure and installed VS 2013 Premium with update 2 on it. Then I tried to register my Lumia 1020 (WP 8.1 installed) using "Windows Phone Developer Registration 8.1" but it says "Unable to connect to a phone. Make sure that the Windows Phone IP over USB Transport (IpOverUsbSvc) service is running.

So... I checked, the service is running indeed, but the Lumia phone on the VM's File Explorer shows up as a "MTP Device". I wonder what's wrong? But my local machine recognizes the phone.

  • To have 8.1 installed at the moment that would mean the phone is already developer unlocked, as you can currently only get 8.1 on the Developer Preview program.

  • @RowlandShaw, yes that's what I did.

  • So what are you trying to do, if you've already unlocked your phone?

    @RowlandShaw, I'm trying to register the phone so that I can develop apps and then test on it.

  • But you must have done that to get 8.1 on it?

"Windows 8.1 VM on Azure" <- I think this is your problem. You're RDPing into an Azure VM? That doesn't sound like it will work. There's some information about using a local VM here, which I think is your best bet if you don't want to install Windows 8.1 on your local machine.

  • Why would a local VirtualBox VM would work but not a Azure VM? My local hardware doesn't have enough resource to host a Windows 8.1 guest, that's why I went with Azure VM.

    There would be no way for a VM running on Azure to communicate with your phone connected to a local PC. The WP8 SDK assumes the phone has a local/physical connection! May 18, 2014 at 14:48
