Custom IEndpointBehavior.cs

using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;

namespace APIServiceConsumer.Services
{
    public class CustomInspectorBehavior : IEndpointBehavior
    {
        private readonly ClientMessageInspector clientMessageInspector = new ClientMessageInspector();

        public string LastRequestXml
        {
            get { return clientMessageInspector.LastRequestXml; }
        }

        public string LastResponseXml
        {
            get { return clientMessageInspector.LastRequestXml; }
        }

        public void AddBindingParameters(
            ServiceEndpoint endpoint,
            System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
        {
        }

        public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
        {
        }

        public void Validate(ServiceEndpoint endpoint)
        {
        }

        public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
        {
            clientRuntime.MessageInspectors.Add(clientMessageInspector);
        }
    }
}

Fixed bad reference to the wrong class. Updated now to use the correct MessageInspector
