How do you use the Data Exchange API Clinet without getting errors on the NewClient method

I've got a simple Visual Studio program which references the NeotysRestDataExchangeAPI. I have successfully built the solution which uses the NewClient and TimerBuilder.Start/Stop.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Neotys.DataExchangeAPI.Model;
using Neotys.DataExchangeAPI.Client;

namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
IDataExchangeAPIClient client = DataExchangeAPIClientFactory.NewClient("http://IBA-SP4-RK:7400/DataExchange/v1/Service.svc/"...;);
// IDataExchangeAPIClient client = DataExchangeAPIClientFactory.NewClient("http://IBA-SP4-RK:7400/DataExchange/v1/Service.svc/";);

for (int i = 0; i < 10; i++)
{
TimerBuilder timer1 = TimerBuilder.Start("Script1", "Timer1");
System.Threading.Thread.Sleep(1000);
client.AddEntry(timer1.Stop());
}
}
}
}

However when I run the .exe from with NeoLoad using the End User Experience Action I get the following Error. I have tried it with both the API Key set and not set within the REST API Project settings.

I reproduce your issue, you need to provide a context when creating the client.

ContextBuilder cb = new ContextBuilder();
cb.Hardware = "test";

IDataExchangeAPIClient client = DataExchangeAPIClientFactory.NewClient("http://IBA-SP4-RK.home:7400/DataExchange/v1/Service.svc/&...;, cb.build());

This issue will be fixed in next version.

It look's like a dependency issue. What is your .NET version?
How are you referencing the Neotys API dependencies? With NuGet?

Alexis,
Thanks for answering.
The .Net version is 4.7.0305. I'm running VS version 15.7.4.

I added the reference to to the API from NeoLoad
as follows.
Are you say there are dependencies to this?
C:\Program Files\NeoLoad 6.5\api\Data Exchange API Client\Csharp\NeotysRestDataExchangeAPI.dll

Yes are also dependencies to NeotysRestDataExchangeAPI.dll, located in C:\Program Files\NeoLoad 6.5\api\Common\Csharp.

Alexis,
I added NeotysRestCommonAPI.dll to the reference. Also I noted that I should've targeted
http://IBA-SP4-RK.home:7400/DataExchange/v1/Service.svc/
and not
http://IBA-SP4-RK:7400/DataExchange/v1/Service.svc/

The error that I'm getting now is
