I am using a .NET API to connect to WCF Services and it works fine in Visual Studio but not in LinqPad.

I am using the same code and referencing the same app.config and DLL files in both Visual Studio and in Linqpad.
Everything is running on my local computer.
The api is using .Net Framework 4.8, so I am using LinqPad 5
The service is up and running at http://localhost:2001/GenericService and the endpoint configuration looks ok

What can be the cause of this? wish I had more info to share but don't know where to look. I have tried to debug but found nothing of value more than it produces the error when getting the request

here is the error from LinqPad dump

Failed to communicate with *** Services. Failed to communicate with server. The caller was not authenticated by the service. The request for security token could not be satisfied because authentication failed.
   at System.ServiceModel.Security.SecurityUtils.ThrowIfNegotiationFault(Message message, EndpointAddress target)

Does your WCF service use Windows authentication? – Selim Yildiz Jan 19 '22 at 20:14
No. I specify username and password which works when in visual studio – Thomas Adrian Jan 19 '22 at 20:53

thx, tried everything I think, but still couldn't get it to work. I have moved on, back in VS – Thomas Adrian Jan 25 '22 at 16:11
