Can not build my scence in Unity when using Opc.Ua.Core.dll.

I built a relatively simple robot in Unity, and I referenced the UA .NetStandard library in it, which includes some dll files in the Assets/Plugins. When I tried to run it inside the Unity Editor, there is no problem with the scripts in it, the OPC UA server works fine, and the publish subscription works fine too. But when I want to compile them into an executable .exe file independently, Unity pops up some errors:

I'm using IL2CPP to be my backend, and using the .Net Standard 2.1.

I wonder if anyone has tried a similar job and can suggest ideas to solve this problem, I would be very grateful !

 

So all I have to do is find these dependencies and put them in the Asserts/Plugins and see if the compilation results are different? Let me try that ! Thanks!

Also, I found that BouncyCastle.Crypto does not have a .Net Standard version, It only contains the .Net Framwork 4.0 version.

 

After adding Newtonsoft.Json (BouncyCastle.Crypto and System.Formats.Asn1 I've added before), the error messages have changed as below:

My guess is that BouncyCastle.Crypto does not have a .Net Standard version (I've mentioned before), is that any possible solution?

 

I've used the Portable.BouncyCastle, most of the problems mentioned before disappered. But It still have serveal errors:

I discovered that the issue is in this DLL file (TDx.TDxInput.dll). Have you encountered any issues with IL2CPP errors after using this DLL? If you can tell me how to fix it, I would be very grateful!
