Optano.Modeling not working with MipCL

I just starting to test the optano.modeling library and I created a new console application with the packages:

• Optano.Modeling
• Optano.Modeling.Gurobi

I copied the default program showed in Optano page (http://docs.optano.net/modeling/current/userDoc/getting_started/step_install_primer.html) and everything works flawless.

This is the program.

using System.Diagnostics;
using OPTANO.Modeling.Optimization;
using OPTANO.Modeling.Optimization.Enums;
using OPTANO.Modeling.Optimization.Solver.Gurobi80;

namespace optanodemo
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var scope = new ModelScope())
            {
                var model = new Model();
                var x = new Variable("x");
                var y = new Variable("y");
                model.AddConstraint(x + y >= 120);
                model.AddObjective(new Objective(2*x + 3*y));

                using (var solver = new GurobiSolver())
                {
                    var solution = solver.Solve(model);
                }
            }
        }
    }
}

After that I decided to change the solver (because I don't want to pay the Gurobi right now) to MipCL 1.41, leaving the code like this:

using System.Diagnostics;
using OPTANO.Modeling.Optimization;
using OPTANO.Modeling.Optimization.Enums;
using OPTANO.Modeling.Optimization.Solver.MipCL141;

namespace optanodemo
{
    class Program
    {
        static void Main(string[] args)
        {
            using (var scope = new ModelScope())
            {
                var model = new Model();
                var x = new Variable("x");
                var y = new Variable("y");
                model.AddConstraint(x + y >= 120);
                model.AddObjective(new Objective(2*x + 3*y));

                using (var solver = new MipCLSolver())
                {
                    var solution = solver.Solve(model);
                }
            }
        }
    }
}

The code compiles but when I run it, I received the exception:

Unhandled Exception: System.TypeInitializationException: The type initializer for

After 5 hours trying to put this to work I decided to write here to see if anyone has had a similar problem. This is what I tried:

• I checked my application folder and the file MipCL141WrapperCpp.dll is in the folder
• I downloaded the MipCL library version 1.41 from http://www.mipcl-cpp.appspot.com/download.html and I installed several times.
• I copied all the MipCL installed files to my application folder
• I set my application build to x64 instead of Any
• I dissassembled the MipCL141WrapperCpp.dll to check any other possible dependency and I saw that the code has references to mipcl.dll, VCRUNTIME140D.dll and ucrtbased.dll. I also copied those files to my application folder.

Is there anything additional you think I can try?

Visual Studio 2017 did not install the file ucrtbased.dll in the windows\system32 folder. It only installs the file ucrtbase.dll.

I downloaded this file from internet and added it to the application folder and everything started to work smoothly.
