I successfully installed the Windows Phone 8 SDK and also enabled Hyper-V successfully.But when I was deploying the PetSounds app on Emulator, the virtual phone displayed "Windows Phone OS is starting" and took a long time before the emulator shut itself down and I got the error message : "App deployment failed. Please try again.". I searched msdn site for it and tried everything I could from troubleshooting(defragmented, ran chkdsk utility, am not using VHD) to checking my Hyper-V virtual adapter settings but still it doesn't works. What should I do to fix this??
