Dedicated Server build fails when using Entities package

--

-

Reproduction steps:
1. Open the “ReproProject“ project
2. Open the Build Settings window (File > Build Settings)
3. Switch to the Dedicated Server platform
4. Build the project

Expected result: The project builds
Actual result: Build fails with compiler errors thrown in the Console window

Reproducible with: 2022.3.16f1, 2022.3.18f1
Not reproducible with: 2022.3.15f1
Couldn’t test with: 2021.3.34f1, 2023.2.6f1, 2023.3.0b4 (due to compilation errors)

Reproducible on: Windows 11 Pro (22H2)
Not reproducible on: No other environment tested

  1. Resolution Note:

    Unity does not support serializable types that have different fields for Editor vs Player. There were some cases previously where the Editor didn't warn properly about violations to that rule and there was recently a fix for it that seems to expose the following issue in the com.ourpalm.ilruntime package:

    In this case, there is a type "RegisterFrameInfo" that contains a field with a type that can be "List<object>" when DEBUG define is active or "UncheckedList<object>" when it's inactive.

    Please notice that the former is not serializable while the latter is. So it looks like Editor is using DEBUG while the build is not, causing RegisterFrameInfo being serialized differently in Editor vs Player.
