Question

I get an error on the client for my wcf service hosted by my console app. Now this works within my browser but not in my win forms which is a simple button textbox and label:

    public ServiceReference1.Service1Client testClient = new ServiceReference1.Service1Client();

    private void button1_Click_1(object sender, EventArgs e)
    {
        label1.Text = testClient.GetData(Convert.ToString(textBox1.Text));
    }

The error I get is:

There was no endpoint listening at http://localhost:8000/hello that
could accept the message. This is often caused by an incorrect address
or SOAP action. See InnerException, if present, for more details.

Host console app code:

class Program
{
    static void Main(string[] args)
    {
        WebHttpBinding binding = new WebHttpBinding();
        WebServiceHost host =
        new WebServiceHost(typeof(Service1));
        host.AddServiceEndpoint(typeof(IService1),
        binding,
        "http://localhost:8000/hello");
        host.Open();
        Console.WriteLine("Hello world service");
        Console.WriteLine("Press <RETURN> to end service");
        Console.ReadLine();
    }
}

Client App.cofig file code:

In order to access a RESTful service you can use the below code:

private string UseHttpWebApproach<T>(string serviceUrl, string resourceUrl, string method, T requestBody)
        {
            string responseMessage = null;
            var request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest;
            if (request != null)
            {
                request.ContentType = "application/xml";
                request.Method = method;
            }    

            if(method == "POST" && requestBody != null)
            {                    
                byte[] requestBodyBytes = ToByteArrayUsingJsonContractSer(requestBody);                
                request.ContentLength = requestBodyBytes.Length;
                using (Stream postStream = request.GetRequestStream())
                    postStream.Write(requestBodyBytes, 0, requestBodyBytes.Length);

            }

            if (request != null)
            {
                var response = request.GetResponse() as HttpWebResponse;
                if(response.StatusCode == HttpStatusCode.OK)
                {
                    Stream responseStream = response.GetResponseStream();
                    if (responseStream != null)
                    {
                        var reader = new StreamReader(responseStream);

                        responseMessage = reader.ReadToEnd();
                    }
                }
                else
                {
                    responseMessage = response.StatusDescription;
                }
            }
            return responseMessage;
        }

ServiceUrl : http://localhost:8000

ResourceUrl : hello/yourstring

Method : GET

RequestBody: Null
