I have x64 windows 8.1 pro, but the system doesn't support SLAT. So this means that I can develop WP8 apps, but I have to test app on physical devices. I have installed visual studio 2013 Update 2, but on opening new project to develop WP8 apps, options are coming to develop only WP8.1 apps. So, where is the SDK for WP8 as I had checked WP8 sdk during installation.
