ServiceHost only supports class service types

Question

I have a service named WcfService2 (original i know) which has an IService.cs file with a public interface:

namespace WcfService2
{
    [ServiceContract]
    public interface IService1
    {    
        [OperationContract]
        [WebGet(UriTemplate = "/{value}")]
        string GetData(string value);            
    }
}

I then have my public class Service1.svc.cs file which returns a string for the value like so:

namespace WcfService2
{
    public class Service1 : IService1
    {
        public string GetData(string value)
        {
            return string.Format("You entered: {0}", value);
        }
    }
}

I am now trying to host this service with a console app like so:

namespace Host
{
    class Program
    {
        static void Main(string[] args)
        {
            WebHttpBinding binding = new WebHttpBinding();
            WebServiceHost host =
            new WebServiceHost(typeof(IService1));
            host.AddServiceEndpoint(typeof(IService1),
            binding,
            "http://localhost:8000/Hello");
            host.Open();
            Console.WriteLine("I DONT LIKE REST!");
            Console.WriteLine("Press <RETURN> to KILL REST FOR GOOD");
            Console.ReadLine();
        }
    }
}

But I get an error after I run it:

ServiceHost only supports class service types.

So this obviously relates to my IService being of public interface type. But I dont know how else to create it, when I first created the WCF Service application it gives you the two standard files IService and Service.svc files if I delete either or, and only Implement this solution in one class when I try to add the web service in local soultion nothing is found.

Is there a way to fiddle with the host code?

Answer 1

I suggest that you change this:

WebServiceHost host = new WebServiceHost(typeof(IService1));

to this:

WebServiceHost host = new WebServiceHost(typeof(Service1));
