Development Environment Installation Instructions:
1, requires Windows 8 64-bit pro or Enterprise version
2, need visual Studio (express to Ultimate can, of course, Ultimate best)
3, requires Windows Phone 8 SDK
4, need to turn on Hyper-V and Slat technology (need CPU support, generally, I3 above support)

It is important to note that:
The 1,windows Phone 8 SDK includes the Windows Phone 7.1 SDK, which means you can select the target platform when you install the WP8 SDK to create a new project. So it is strongly established that developers directly install WP8 SDK.
2, in Windows 7 and earlier versions of Windows can not currently develop Windows Phone 8, nor have heard the way to achieve the purpose of cracking.
