Aras.OAuth.Model error when trying to connect using IOM.dll in a .Net Core app

I'm trying to integrate the IOM.dll into a .net core application and I get the error below.

"Could not load file or assembly 'Aras.OAuth.Model, Version=, Culture=neutral, PublicKeyToken=524d880b05474146'. The system cannot find the file specified."

I have the following code with the variable values changed:

string serverUrl = "">server/.../InnovatorServer.aspx";
string database = "DataBaseName";
string userName = "user";
string password = "userPassword";

HttpServerConnection connection = IomFactory.CreateHttpServerConnection(

Item loginResult = connection.Login(); //Get Error Here

Innovator inn = IomFactory.CreateInnovator(connection);

I have added the IOM.dll, Aras.Net.dll, and Aras.Diagnostics.dll as refrences from the Aris installation folder, and added a using Aras.IOM.
