title: No error messages with Fluent Validation in ServiceStack
body: <p>I am just starting to familiarise myself with ServiceStack and have come upon FluentValidation. I have followed the introductions and created a small Hello App. </p>
  
  <p>My problem is that when I try to validate the request DTO <strong>no error messages</strong> are returned to describe how it failed validation, only a blank Json object <code>{}</code>.</p>
  
  <p>Myself, I think the validation is autowired to the DTO so there should be no need for me to write any extra code.</p>
  
  <p>The answer is probably blatant but I cannot see it. Any help would be greatly appreciated. My code is below: </p>
  
  <pre><code>namespace SampleHello2
  {
      [Route("/hello")]
      [Route("/hello/{Name}")]
      public class Hello
      {
          public string Name { get; set; }
      }
  
      public class HelloResponse
      {
          public string Result { get; set; }
      }
  
  
      public class HelloService : Service
      {
          public object Any(Hello request)
          {
              return new HelloResponse { Result = "Hello, " + request.Name };
          }
      }
  
      public class HelloValidator : AbstractValidator&lt;Hello&gt;
      {
          public HelloValidator()
          {
              //Validation rules for all requests
              RuleFor(r =&gt; r.Name).NotNull().NotEmpty().Equal("Ian").WithErrorCode("ShouldNotBeEmpty");
              RuleFor(r =&gt; r.Name.Length).GreaterThan(2);
          }
      }
  
      public class Global : System.Web.HttpApplication
      {
          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)
              {
                  //Enable the validation feature
                  Plugins.Add(new ValidationFeature());
                  container.RegisterValidators(typeof(HelloValidator).Assembly);
                  //register any dependencies your services use, e.g:
                  //  container.Register&lt;ICacheClient&gt;(new MemoryCacheClient());
              }
          }
  
          //Initialize your application singleton
          protected void Application_Start(object sender, EventArgs e)
          {
              new HelloAppHost().Init();
          }
      }
  }
  </code></pre>
  
  <p>P.S. Really enjoying using ServiceStack, It really is a fantastic project so thanks.</p>
  
  <p><strong>Edit</strong></p>
  
  <p>So for example:</p>
  
  <p>Calling: <code>http://localhost:60063/hello/Ian?format=json</code> returns <code>{"Result":"Hello, Ian"}</code>.
  Whereas Calling: <code>http://localhost:60063/hello/I?format=json</code> returns <code>{}</code>.</p>
  
  <p>The second call returns <code>{}</code> where I was expecting auto generated error messages.</p>
