Description

Hi, I am trying to run the sample MRTK project on Hololens2. I opened the project in Unity 2020.3.22f1 version. Then, I added Azure Object Anchors feature using the MixedRealityFeatureTool and modified my Build settings to Universal Windows Platform. But I am facing some errors -

Screenshots

I've attached the Screenshots of these errors.

Development information (please complete the following information)

OS: Windows 10
Development Platform\Version: Visual Studio 2019, Unity 2020.3.22f1

Additional context

Error 1 & Error 2 pictures are the errors faced by me in the sample project.
Error 3 pictures consist of the errors that occurred when I imported the Object Anchors Folder to a new Empty project.

Sorry to hear you're facing issues. Did you follow the instructions here to update the code for Unity 2020? There are breaking changes between Unity 2019 and 2020, so it's hard to make a sample that seamlessly works with both without overcomplicating it.

We're gonna take a look at making things easier for Unity 2020. Internal reference number is 38627628.

Closing as a duplicate of #17 where we'll track these issues.
