Question Errors on Visual Studio 2022 when building mixed-reality app to Hololens 2

Hello everyone,

I'm trying to build and deploy a mixed-reality app I've developed in Unity to the MS Hololens 2, but I'm running into some errors. I'm using Unity 2021.3.13f1 and Visual Studio 2022 version 17.4.3, and I used both Microsoft's Mixed-Reality Toolkit and the Vuforia plugin to develop my app. I'm following the instructions on this webpage to deploy with Visual Studio: https://learn.microsoft.com/en-us/w...dvanced-concepts/using-visual-studio?tabs=hl2

This is the output I'm getting on Visual Studio:

I'm not sure where the problem is, so if someone could help me out I would be really thankful!

 

Thank you! Sorry for not seeing that thread before.
