VS Error: Type 'CoreApplicationView' and 'CoreWindow' Defined in assembly that is not referenced

edited August 2017 in Questions And Answers

This has been bugging me for two days. Getting error when building the unity project in Visual Studio 2017. I want to deploy the app on my Hololens. I don't need the emulator.
I installed everything, also reinstalled several times.
I followed these instructions:

But still getting two errors:
'CoreApplicationView' and 'CoreWindow'
The type is defined in an assembly that is not referenced. You must add a reference to assembly 'Windows, Version=, Culture=neutral, PublicKeyToken=null, ContentType=WindowsRuntime'.

This is the second install. In the first install, I updated all these 4 before as well, and still didn't work.



  • I have recently encountered this problem, may I ask how to solve it in the end,thank you. :smile:

  • Is this problem resolved? I am still having this problem with Unity 2017.3.1f1 !!! I just followed Hololens 100 Tutorial and I am blocked by this error!

  • Is there anyone supporting on this forum? I haven't seen any response from Microsoft, yet.
