JIT compile method

[rubentorresbonet]

Hey, thank you for your great work! My code runs great on PC but not on XBOne. The printed error:

ExecutionEngineException: Attempting to JIT compile method 'System.Collections.Generic.GenericEqualityComparer`1<Newtonsoft.Json.Serialization.DefaultSerializationBinder/TypeNameKey>:.ctor ()' while running with --aot-only.

Do you have any idea? Thank you again!

Thanks for reporting error. I'll take look at the case. Before my work, try adding link.xml to your project.

This problem is not reproducible with Unity 5.2 and IL2CPP build option. Dynamic code generation bug with this problem is rooted in mono-aot but mono-aot is replaced with unity-il2cpp now. So it's hard to see this problem again.

I want to know more detail of this problem.

• What version of unity do you use to build your app?
• What unity build setting do you use?
• With your build setting, do "JsonNetSample.unity" in package run successfully?
