    Was having issues using newtonsoft JSON library in my project which I have used before and traced it to the IL2CPP implementation. Switched project to use Mono for scripting backend and it works fine.

    IL2CPP does not support JIT compilation or dynamic code generation, so the the System.Reflection.Emit namespace is not supported. If you need to use dynamic code generation, then Mono is the proper choice for your project.
