The emulator on Windows Phone 8 and Hyper-V SDK

Posted on: 30-10-2012 | 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 newly released SDK for Windows Phone 8 is only possible to install it 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, it is not an emulator to use as we had in Windows Phone 7.5, but an image SO virtualized through Hyper-V technology and Microsoft 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 greater stability and better performance, on the other hand throwing various emulators while a rather more easily than before doing homework, managing the images of our Windows Phone emulated are now manageable and not as before they were a single file and sometimes we had to stick with the session files that were hanged and others ...


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


You go first on the forehead, Visual Studio warns me kindly 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 check whether our system is capable of running Hyper-V and if we have the hardware required to do so. 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 the best is unburden this small Microsoft utility called Coreinfo to check all these requirements.

Just after unburden Coreinfo, run it on the command line with administrator, parameter -v

  C: \> Coreinfo.exe -v 

This showed us a series of data capabilities of our processor.


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

Finally we must make another check, in this case running Coreinfo without any input parameter.

  C: \> Coreinfo.exe 

Among all the features we should look presents the NX option, which will tell us if we have the ability to DEP (Hardware-Based Data Executivo Prevention) or not, with an asterisk.


After checking everything, we should know that we have to have an asterisk in the 3 characteristics mentioned and see Hypervisor is present, if this is not true and we can start thinking about buying another computer or simply forget to test your applications in the emulator Windows Phone 8.

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


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



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


Here our brand new emulator ready to start testing our applications for 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 supported because if it works on my PC host ... do not know how ... in a virtual machine. Any idea ???

sorry to say that it screwed up my microsoft. I've spent a week to install the emulator and I have not succeeded in the end I will be developing in android is infinitely easier to launch an emulator.
Either this changes or grows not think much of the microsoft store

Excellent all Lumnia buy Nokias, Android is very, very bad in low range, good IOS overpriced and the truth is far from satisfactory, Lumnia Nokia 520 is excellent and cheap, no Android in this segment compared to the same fluidity system is excellent, no lags as Android and super awesome, totally recommended.
