OpenCVSharp in Unity error

Hi everyone,

I am trying to add OpenCVSharp to a unity project. I have downloaded the dll-files from here: https://github.com/shimat/opencvsharp/releases

I have made it work so far that I can use the OpenCVSharp package and everything in it in Visual Studio, when editing a script, and it recognizes everything. However, Unity is still giving me an error:

 Unhandled Exception: System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded.

 The following assembly referenced from C:\Users\ah\Documents\P3\Assets\Plugins\OpenCvSharp-3.1.0\OpenCvSharp.Extensions.dll could not be loaded:
      Assembly:   PresentationCore    (assemblyref_index=4)
      Version:    3.0.0.0
      Public Key: 31bf3856ad364e35
 The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (C:\Users\ah\Documents\P3\Assets\Plugins\OpenCvSharp-3.1.0\).
 
 Could not load file or assembly 'PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

I have tried changing the build settings from .NET 2.0 subset to full, but with no success. Any suggestions?
