dll UnsatisfiedLinkError

Hi! I'm experimenting with .NET bindings for the robotic framework ROS2 (https://github.com/esteve/ros2_dotnet). After succesfully compiled ros2_dotnet for Windows with VS2017 and included the appropriate generated .dll's to the Plugins folder of my Unity project, I get this UnsatisfiedLinkError at runtime:

 UnsatisfiedLinkError: rcldotnet_native.dll
 ROS2.Utils.DllLoadUtilsUWP.ROS2.Utils.DllLoadUtils.LoadLibrary (System.String fileName) (at <1acf2d248c3a4b93a401535c1766d2de>:0)
 ROS2.RCLdotnetDelegates..cctor () (at <88f86c16a6e94fecb0df9ed8835da5e2>:0)
 Rethrow as TypeInitializationException: The type initializer for 'ROS2.RCLdotnetDelegates' threw an exception.
 ROS2.RCLdotnet.Init () (at <88f86c16a6e94fecb0df9ed8835da5e2>:0)
 ConsoleApplication.RCLDotnetListener.Main (System.String[] args) (at <b4737fe732bf4837b6f6422c784e89a0>:0)
 rcldotnetlistener.Start () (at Assets/Scripts/rcldotnetlistener.cs:30)

The way I'm trying this example is quite simple:

 using UnityEngine;
 using ConsoleApplication;
 public class rcldotnettalker : MonoBehaviour
 {
     string[] args;
     void Start()
     {
         RCLDotnetTalker.Main(args);
     }
 }

Working with Unity 2018.2, Scripting Runtime Version .NET 4.x Equivalent, Backend Mono, API Level 4.x .

Maybe have dll's been generated incorrectly for using them on Unity? Maybe are they correctly generated but not correctly referenced just placing them in Plugins folder?

Thank you!
