I have the same issue: in console application works fine while in the form application doesn't work.

This below works file:

class Program
    {
        [ServiceContract]
        public interface IHelloWorldService
        {
            [OperationContract]
            string SayHello(string name);
        }

        public class HelloWorldService : IHelloWorldService
        {
            public string SayHello(string name)
            {
                return string.Format("Hello, {0}", name);
            }
        }

        static void Main(string[] args)
        {
            Uri baseAddress = new Uri("http://localhost:8757/hello");

            // Create the ServiceHost.
            using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))
            {
                // Enable metadata publishing.
                ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
                smb.HttpGetEnabled = true;
                smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
                host.Description.Behaviors.Add(smb);

                host.Open();

                Console.WriteLine("The service is ready at {0}", baseAddress);
                Console.WriteLine("Press <Enter> to stop the service.");
                Console.ReadLine();

                // Close the ServiceHost.
                host.Close();
            }
        }
    }

This below doesn't work:

public partial class Form1 : Form
    {
        [ServiceContract]
        public interface IHelloWorldService
        {
            [OperationContract]
            string SayHello(string name);
        }

        public class HelloWorldService : IHelloWorldService
        {
            public string SayHello(string name)
            {
                return string.Format("Hello, {0}", name);
            }
        }

        public Form1()
        {
            InitializeComponent();
        }

        private void Loading(object sender, EventArgs e)
        {
            Uri baseAddress = new Uri("http://localhost:8758/hello");

            // Create the ServiceHost.
            using (ServiceHost host = new ServiceHost(typeof(HelloWorldService), baseAddress))
            {
                ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
                smb.HttpGetEnabled = true;
                smb.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
                host.Description.Behaviors.Add(smb);
                host.Open();
            }
        }
    }
