Self-host WCF Service. Error: Cannot obtain Metadata from http://localhost/TaskService If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.

Question

Hi. I have created a WCF service. And I'm trying to self-host it in Console App like this:
var builder = new ContainerBuilder();
builder.RegisterType<Repository>().As<IRepository>();
builder.Register(c => new TaskService
(c.Resolve<IRepository>())).As<ITaskService>();
var container = builder.Build();

        string baseaddr = "http://localhost/TaskService/";
        Uri baseAddress = new Uri(baseaddr);
        using (ServiceHost host = new ServiceHost(typeof(TaskService), baseAddress))
        {

            ServiceMetadataBehavior serviceBehavior = new ServiceMetadataBehavior();
            serviceBehavior.HttpGetEnabled = true;
            serviceBehavior.MetadataExporter.PolicyVersion = PolicyVersion.Policy15;
            host.Description.Behaviors.Add(serviceBehavior);

            host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexHttpBinding(), "mex");
            host.AddServiceEndpoint(typeof(ITaskService), new WSHttpBinding(), "");

            host.AddDependencyInjectionBehavior<ITaskService>(container);

            host.Open();
        }

When ConsoleApp is run, I'm trying to test my wcf by using WcfTestClient. And I get an error:
Error: Cannot obtain Metadata from http://localhost/TaskService If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.

Any help would be really appriciated!

Hi @Golomazdina Natalya ,
I think you can create a try block that will catch any exceptions thrown while the service is running.
Make sure baseaddr is correct.
For metadata about using the code publishing service, you can refer to the tutorial.

You have got to be kidding me. Whomever is responsible for writing this WCF abomination should be put in a dungeon with Bill Gates. That also goes for whomever is ultimately responsible for the God-awful documentation at MS. Literally everything is incomplete, utterly unexplained, and/or simply does not work.
