Question

So trying to create a rest service but I keep getting an error:

If I try to run it in a browser I get : The type 'WcfService2.Service1', provided as the Service attribute value in the ServiceHost directive could not be found.

namespace WcfService2
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
    [ServiceContract]
    public class HelloWorldService
    {
        [OperationContract]
        [WebGet(UriTemplate = "")]
        public string HelloWorld()
        {
            return "Hello world!";
        }
    }
}

namespace WcfService2
{
    // NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.

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

You’re defining a REST-style WCF service using the WebHttpBinding.

The WCF Test Client is only usable for SOAP services – not for REST services. REST services can be tested using your regular browser, or tools like Fiddler.

The error message you’re getting would almost indicate that you have a *.svc lying around somewhere, too, that gets in your way. Is that the case?
