NotSupportedException with il2cpp backend on 2018.1 Beta 9, SerializedScriptableObject

[Former user]

Hello. Using odin on the Mono backend works fine but causes an exception with il2cpp. (I also generated the DLLs before-hand)

Which platform is this compiled for?

Depending on the platform we have the emitting enabled or disable by default. But emitting is not supported on the IL2CPP backend, so you'll manually have to change the DLL import settings. Unfortunately, Unity does not currently offer a way to configure the DLL import settings based on scripting backend.

However, to get around this all you need to do is exclude the NoEditor DLLs and enable the NoEmitNoEditor DLLs instead.

To do this, go to 'Plugins > Sirenix > Assemblies > NoEditor', select the Sirenix.Serialization and Sirenix.Utilities files in there and disable the platforms you're having issues with. Then select the Sirenix.Serialization and Sirenix.Utilities files in 'Plugins > Sirenix > Assemblies > NoEmitAndNoEditor' and enable the platforms on these DLLs.

That should solve your issue :)

I'm going to leave this open until you can verify that this has solved your issue.

Hello, sorry for being late, your fix works. Thanks!

Works for me too. But you need to make some tutorial in the FAQ on the landing page or somewhere in the section about AOT. Because I spent a lot of time before finding this issue. In my case, it was Android compilation with Scripting Runtime Version .NET 4.x. Equivalent, Api Compatibility Level .NET 4.x, Scripting Backend IL2CPP
