No configuration Wcf host and client

Using Exception in Wcf should be very caucious, as I blogged before, wcf exception should be marked as Serializable, and implement all 4 ctor from base exception class. An unit-test for each exception might be overkill, but it’s worth to try.

In-proc wcf host is neat for this purpose, by using channel Factory, client side doesn’t need configuration either.

    public class MyDataNotFoundExceptionSpecs
    {
        private readonly ServiceHost _host;
        private const string _url = "net.tcp://localhost:9000/TestException";

        public MyDataNotFoundExceptionSpecs()
        {
            _host = new ServiceHost(typeof(TestService));

            _host.AddServiceEndpoint(typeof(ITestService),
                new NetTcpBinding(), _url);
            _host.Open();
            Console.WriteLine("wcf service started.");
        }

        ~MyDataNotFoundExceptionSpecs()
        {
            _host.Close();
        }
            private ChannelFactory<ITestService> channelFactory;

            {
                channelFactory = new ChannelFactory<ITestService>(
                   new NetTcpBinding(),
                   new EndpointAddress(_url));
            }

        {
            ITestService proxy = channelFactory.CreateChannel();

            proxy.Ping("Frank");

          }

    }

    public class TestService : ITestService

        public void Ping(string user)
        {
            throw new FaultException<MyDataNotFoundException>(new MyDataNotFoundException());
