How to set up .net core teradata connection in c#?

Question

I am trying to connect to Teradata with dotnet core driver: Teradata.Client.Provider 17.10.2.

I have set-up a Teradata Vantage Express instance and I am able to connect to it via DBeaver (JDBC) with default credentials dbc/dbc.

Based on docs and this answer https://stackoverflow.com/a/21267030/3120219 I'm now trying to connect via a C# driver with the following code:

using System;
using Teradata.Client.Provider;
using Xunit;

namespace MyProject.Test
{
  public class TeradataConnectionTest
  {
    public void TestConnection()
    {
      var connectionStringBuilder = new TdConnectionStringBuilder
      {
        DataSource = "localhost",
        Database = "dbc",
        UserId = "dbc",
        Password = "dbc",
        AuthenticationMechanism = "TD2" // Tried also "LDAP" and "TDNEGO"
      };

      using TdConnection cn = new TdConnection();
      cn.ConnectionString = connectionStringBuilder.ConnectionString;
      cn.Open();  // exception here

      TdCommand cmd = cn.CreateCommand();
      cmd.CommandText = "SELECT DATE";

      using (TdDataReader reader = cmd.ExecuteReader())
      {
        reader.Read();
        DateTime date = reader.GetDate(0);
      }
    }
  }
}

But I'm receiving this exception on connection open:

Teradata.Client.Provider.TdException
[.NET Data Provider for Teradata] [115057] The WebSocket handshake response is invalid. Details: Unexpected or invalid response received.

It seems that the client is trying to connect to the webserver instead of the data provider services.

What am I missing ?
