When I upgraded Visual Studio 2017 to 15.8.2 it crashed and I had to wipe everything and reload. Since then I have not been able to get the Windows IoT Extensions for the UWP. When I click on the reference in my project the Windows IoT Extension shows up with a yellow triangle. 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. 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. Any help would be greatly appreciated.
