#FileNotFoundException with JetBrains.Annotations when using Essential Kit 3.4.2 in Unity 2022.3.62f

When launching the app in the Unity Editor, I get:

#

FileNotFoundException: Could not load file or assembly
'JetBrains.Annotations, Version=4242.42.42.42, Culture=neutral,
PublicKeyToken=1010a0d8d6380325'

#

Stacktrace points into Essential Kit’s TypeCache doing reflection.

The problem comes from the Rider Unity Editor Plugin:

#

~/Rider/plugins/rider-unity/EditorPlugin/JetBrains.Rider.Unity.Editor.Plugin.Net46.Repacked.dll
Type: JetBrains.Rider.PathLocator.RiderPathLocator+ToolboxState

wild sentinel
#

We use TypeCache for Domain Reload handling - for safe cleanup.

That DLL references a fake JetBrains.Annotations (4242.42.42.42).
Unity can’t resolve it → reflection explodes.

Impact:

Essential Kit 3.4.2 editor code (e.g. DomainReloadManager) crashes on domain reload.

Adding a separate JetBrains.Annotations.dll doesn’t help (conflicts with UnityEngine.CoreModule).

Current workarounds:
Skip Rider assemblies during reflection

Do you have complete log trace?

I will also check once on my end as I expect only VoxelBusters namespace classes to be considered.

#

In my project, the attribute is checked for 44458 types, as all assemblies are scanned)

#

It seems to me that it is more correct to scan only assemblies from Voxel Busters.

Yea, I will check it. I expect the same. My partner wrote it and I recall fixing some issues in it sometime back. Need to see why other than VB's classes + System are considered.
