  • Hi DamonSWT,

    Please check whether you have installed the Update 1 for your Visual Studio. If not, please download and install from below link.

    https://www.microsoft.com/en-us/download/details.aspx?id=49989

    Then please check your Windows 10 is set to Developer mode in Settings -> Updates and Security -> For Developers.

    Next, please open the Visual Studio setup from Control Panel -> Programs and Features -> Visual Studio 2015 -> Change -> Modify. Whether you have installed the Windows 8.1 and Windows Phone 8.0/8.1 Tools for your Visual Studio 2015.

    Best Regards,
