First, download the official Microsoft SDK8.0 installation program, and run the program until the download is completed (it is recommended to download the offline installation package here to save time and avoid reporting an error during installation, resulting in uncertain direction). You must choose Simplified Chinese version to download, otherwise the development tool will default to English permanently, and cannot be modified and integrated with vs20 12.

Turn on the Hyper-V function (press Windows+X–> Programs and Functions to enable or disable the Windows function, select Hyper-V, and then confirm).

Because the signature date of VS installer is earlier, it is necessary to adjust the system date (between six months and one year ago) when installing SDK, otherwise it will report an invalid signature.

Tip: You may report an error during installation for no reason. At this point, uninstall the installed program and then reinstall it. After the installation is completed, you will continue to deploy the SDK after restarting the computer. After successful deployment, you can find the vs Express program for windows phone.
