csharp aot error in Unity3D iOS

[saviosun]

After fix the bug #394, I find a new bug.

ExecutionEngineException: Attempting to JIT compile method 'Google.ProtocolBuffers.CodedInputStream:ReadEnum<Google.ProtocolBuffers.DescriptorProtos.FieldDescriptorProto/Types/Label> (Google.ProtocolBuffers.DescriptorProtos.FieldDescriptorProto/Types/Label&,object&)' while running with --aot-only.

I'm getting this too, any workaround?

We'll have to see if this occurs in the new (experimental) version. I suspect it may, due to the use of expression trees in the new code. Will have to see if I can get hold of a working environment to reproduce and fix...

Unity is simply not supported at the moment. See #644 for details and discussion.
