I've uninstalled and installed VS2017 many times and I think I'm following the IoT instructions to the letter on the install but obviously I'm being thick and missing something. I right click on reference to add reference, go to universal windows (it shows core and extensions), I click extensions and Windows IoT is not there.
In fact, one of the goals for UWP was to enable the same application to run on PC, Xbox, HoloLens, Surface Hub or IoT Core devices. When I click on the reference in my project the Windows IoT Extension shows up with a yellow triangle. Windows 10 IoT Core is a version of Windows 10 that is optimized to run on smaller IoT devices, with or without a display, that allows you to build apps using the rich Universal Windows Platform (UWP). 10 reasons Windows 10 is better than Chrome OS and Mac OS X. Since then I have not been able to get the Windows IoT Extensions for the UWP. Zicom bets big on IoT, eyes revenue of Rs 200 crore by 2020. When I upgraded Visual Studio 2017 to 15.8.2 it crashed and I had to wipe everything and reload.
