CGALDotNet outside of Unityu

[SgtLame]

Hi,
CGALDotNet works like a charm in Unity, but now I need to use it in a standard C# winform project.
Problem is, at the first instruction that uses CGALDotNet:

using CGALDotNet;
using CGALDotNetGeometry;
(...)
List<Point2d> points = new List<Point2d>(); // First CGALDotNet use in the program

the program throws a "System.IO.FileNotFoundException : Could not find file or assembly 'System.Runtime, Version=4.2.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies".
I manually added a reference to the system.runtime.dll file that is used in a Unity project and spent a lot of time trying and searching, but could not find a solution.
Any ideas?
