Is there any way to do this by running a WP8 emulator in a virtual machine? I would really like to publish WP8 apps but I need to do some testing and don't want to pay to upgrade to the pro version of windows. Thanks for any help you can give.
Currently there is no solution for this. You have to have a emulator or a device to test the app and testing on a device is mandatory now. There used to be Nokia Remote Device Access but it is deprecated now. http://developer.nokia.com/resources/remote-device-access
