The emulator on Windows Phone 8 SDK and Hyper-V

Posted on: 10/30/2012 | By: Technology | In: Windows Phone 8


As you all surely know, and if you do not know and I tell you that's why I'm here, the recently released SDK for Windows Phone 8 is only possible to install on machines with 64-bit operating systems.

What is the reason ?, well because surely there will be many, but one of them is that the new emulator to test our applications is not an emulator to use as we had in Windows Phone 7.5, but an image SO virtualized through the Hyper-V Microsoft technology and this technology is only compatible with 64-bit systems as you can see on your requirements .

This to me means a great advantage over previous versions emulator. On the one hand gives it more stability and better performance, on the other hand throwing various emulators while a rather more easily than before doing homework, managing images of our Windows Phone emulated are now manageable and not as before they were a single file and sometimes had to stick with session files that were hanged and others ...


Well, get to work and we will prepare to launch our brand new site emulator and view their full potential.


You go first on the forehead, Visual Studio warns me gently that you may not be enabled in the BIOS support for hardware virtualization, needed to launch Hyper-V and therefore the emulator.

But first serious test whether our system is capable of running Hyper-V and if you have the hardware required for this. I remind you that we need our machines run the Hardware-assisted virtualization , SLAT (Second Level Address Translation) and DEP (Hardware-based Data Execution Prevention).

If this sounds like Chinese and you have no clue what I'm talking maybe it's unburden this small utility for Microsoft, called Coreinfo to check all these requirements.

Just after unburden Coreinfo, run it in the command prompt with administrator permissions, -v parameter

  C: \> Coreinfo.exe -v 

This will show us a series of data capabilities of our processor.


We must ensure we have an asterisk in the last 2 features, capacity and SLAT hardware virtualization presente.y to tell us that the Hypervisor is present.

Finally we should do another check, in this case Coreinfo running without any input parameter.

  C: \> Coreinfo.exe 

Among all the features that presents we must seek the NX option, which will tell us if we have the ability to DEP (Hardware-Based Data Executivo Prevention) or with an asterisk.


Once checked everything, we know we have to have an asterisk in the 3 characteristics mentioned and see Hypervisor present, if this is not the case and we can start thinking about buying another computer or simply forget to test our applications on the emulator Windows Phone 8.

If we are lucky to have all these requirements, we simply go to our system BIOS and enable hardware virtualization is normally disabled. In my case I have simply go to the section CPU features within my BIOS and activate it:


Just a little something more, once verified our system and enabled in the BIOS option virtualization, we add our Windows user to the Administrators group of Hyper-V, to spare any permission issues and others when assigning hardware emulator. To do this we simply go to the equipment manager and section assign the user to the administrators group our Hyper-V.



Well, ready, once completed these steps, the next time you run the emulator debugging, show us the enforcement notice with elevated privileges if not run and Visual Studio with administrator permissions.


Here our brand new emulator ready to start testing our applications to Windows Phone 8.

I have a Hyper-V virtual machine with Visual Studio, but when I install the Windows Phone SDK emulator does not work because I can not install the Hyper-V within a Hyper-V ... .. Apparently I can not work with Windows Phone SDK within an emulator of Microsoft itself.

My computer if you have support because if it works on my PC host ... do not know how to do it in a virtual machine .... Any ideas ???

therefore sorry to say that for me has screwed microsoft. I've spent a week to install the emulator and I have failed in the end I will be developing in android is infinitely easier to launch an emulator.
Either this changes or not grow much think the store of microsoft

Excellent everyone to buy Nokias Lumnia, Android is very, very wrong with low-end, well IOS overpriced and the truth is far from satisfactory, Lumnia Nokia 520 is excellent and cheap, no Android in this segment compared with the same fluidity the system is excellent, no lags like Android and super great, totally recommended.
