Handler for Request not found:

Question

I am building a service stack for the first time: hello world.

I have followed the step by step guide in here:

but it is giving me an error: Handler for Request not found: what could be the missing part? thanks.

here is my global.asax.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.SessionState;
using ServiceStack.ServiceHost;
using ServiceStack.WebHost.Endpoints;

namespace ServiceStack.SearchService
{
    public class Global : System.Web.HttpApplication
    {
        public class Hello { public string Name { get; set; } }
        public class HelloResponse { public string Result { get; set; } }
        public class HelloService : IService<Hello>
        {
            public object Execute(Hello request)
            {
                return new HelloResponse { Result = "Hello, " + request.Name };
            }
        }



        /// Web Service Singleton AppHost
        public class HelloAppHost : AppHostBase
        {
            //Tell Service Stack the name of your application and where to find your web services
            public HelloAppHost()
                : base("Hello Web Services", typeof(HelloService).Assembly) { }

            public override void Configure(Funq.Container container) { }
        }

        protected void Application_Start(object sender, EventArgs e)
        {
            //Initialize your application
            var appHost = new HelloAppHost();
            appHost.Init();
        }


        void Application_End(object sender, EventArgs e)
        {
            //  Code that runs on application shutdown

        }

        void Application_Error(object sender, EventArgs e)
        {
            // Code that runs when an unhandled error occurs

        }

        void Session_Start(object sender, EventArgs e)
        {
            // Code that runs when a new session is started

        }

        void Session_End(object sender, EventArgs e)
        {
            // Code that runs when a session ends. 
            // Note: The Session_End event is raised only when the sessionstate mode
            // is set to InProc in the Web.config file. If session mode is set to StateServer 
            // or SQLServer, the event is not raised.

        }

    }
}

here is my web.config:

There is a small step missing from that list that you need if your going to map the services to a custom path. You can find it here:

To quote the missing step:

You also need to configure the root path in your AppHost.

public override void Configure(Container container)
{
    SetConfig(new EndpointHostConfig { ServiceStackHandlerFactoryPath = "api" });
}

Where "api" is the name of the custom path you are using.
