Path to CoreCLR, 2026: Upgrade Guide

Success
I created a CoreCLR player build that references a game’s .NET Standard C# library containing 1,200 classes. It ran without issue, generating a procedural galaxy with one million star systems. Performance was on par with .NET 10.

Modding
I also noticed that referenced .NET Standard DLLs are now included in build output, which is great news for the modding community. For users coming from IL2CPP, is there a mechanism to keep referenced assembly code in GameAssembly.dll ?
