System.DllNotFoundException: ole32.dll

[ffirenze]

I'm trying to obfuscate a project, and I'm failing the communication library with the series port. The rest of the project, which is a lot of DLL, processes without apparent problems. The DLL has not protections enabled. It works fine on ConfuserEx v1.0.0-2-g5e2bceb version.

• ConfuserEx Version:
  Confuser.Core 1.6.0+447341964f Copyright © 2014 Ki, 2018 - 2022 Martin Karing

• Target Framework:
  .NET 4.0

• Operating System:
  Running on Unix 4.4.0.210, 6.12.0.200 (tarball Tue Jul 11 21:34:53 UTC 2023), 64 bits
  Ubuntu 16.04.7 LTS

Steps to Reproduce:

1. Run "Confuser.CLI.exe mysolution.crproj".

I recently discovered that those DLLs were compiled on Windows. The rest of the project was compiled on Linux, and those libraries are dependencies. I compiled them on Linux with msbuild and it stopped crashing.
