Hey, we are currently evaluating Realm as a Database for our project. However we encountered some issues on UWP ARM64 with Unity.

What happened?

When we are trying to build for HoloLens 2 on UWP ARM64 via Unity, il2cpp throws an linker error

Repro Steps

Create an empty Unity project with Unity 2021.3.5f1 LTS, add Realm via UPM and build for UWP ARM64. After compiling the resulting Visual Studio Solution, we get the error message. iOS and Android seemed to work fine so far.

We already tried to change the obvious parameters like build config (Debug, Release, Master), IL2CPP code generation (smaller faster build, faster runtime) and tried adding the dlls to the link.xml to avoid assembly stripping. Nothing did change.

Version

10.20.0

What type of platform is this?

Cross platform solution, UWP ARM64, Android, iOS

Client OS and Version

Windows 10 and Windows 11 tested with both Visual Studio 2019 and 2022

Code Snippets

We didn't write a single line of code, we just added the dependency
