WCF service interception is not supported

WCF service won’t be hosted if it has an interceptor. Using: Windsor 3.4.0, .Net 4.6.1.

Here is how WCF service is created:

[ServiceContract]
public interface IEmployeeService
{
  [OperationContract, WebInvoke(Method = "GET", UriTemplate = "/get/{value}")]
  string GetData(string value);
}

public class EmployeeService : IEmployeeService
{
  public string GetData(string value)
  {
    return $"You entered: {value}";
  }
}

public interface IWcfInterceptor: IInterceptor { }

public class WcfInterceptor : IWcfInterceptor
{
  // implementation goes here
}

// ...........
// 0. Create windsor container, add wcf facility;
// 1. Register the interceptor component;
// 2. Register the WCF service;
Component.For<IEmployeeService>()
  .ImplementedBy<EmployeeService>()
    .AsWcfService(new RestServiceModel()
      .AddBaseAddresses("http://localhost:30115/employee")
      .AddEndpoints(WcfEndpoint.ForContract<IEmployeeService>()
      .BoundTo(new WebHttpBinding())
      .At("rest"))
    )
    .AsWcfService(new DefaultServiceModel()
      .AddBaseAddresses("http://localhost:30115/employee")
      .AddEndpoints(WcfEndpoint.ForContract<IEmployeeService>()
      .BoundTo(new WSHttpBinding())
      .At("soap")).PublishMetadata(o => o.EnableHttpGet())
    )
    .Interceptors<IWcfInterceptor>() // this is not supported

Hi,

I changed your test to be the following:

[Test]
public void CanCreateServiceHostAndOpenServiceHostWithInterceptor()
{
	using (new WindsorContainer()
		.AddFacility<WcfFacility>(f => f.CloseTimeout = TimeSpan.Zero)
		.Register(
		Component.For<ServiceInterceptor>(), // <-- Removed interface as service type for interceptor
		Component.For<IOperations>()
			.ImplementedBy<Operations>()
			.DependsOn(new { number = 42 })
			.AsWcfService(new DefaultServiceModel().AddEndpoints(
				WcfEndpoint.BoundTo(new NetTcpBinding { PortSharingEnabled = true })
					.At("net.tcp://localhost/Operations"))
			)
			.Interceptors<ServiceInterceptor>()
		))
	{
		var client = ChannelFactory<IOperations>.CreateChannel(
new NetTcpBinding { PortSharingEnabled = true }, new EndpointAddress("net.tcp://localhost/Operations"));
		Assert.AreEqual(42, client.GetValueFromConstructor());
	}
}    

public class ServiceInterceptor : IInterceptor
{
	public void Intercept(IInvocation invocation)
	{
		invocation.Proceed(); // <-- Made sure the invocation proceeds
	}
}

*** Edited ***

If you are interested in getting the underlying values back you have to call invocation.proceed. Also Windsor does not really care that interceptors are registered with IInvocation as a service type, this is more a Castle Core dynamic proxy thing.

Hope this helps! 😃

@fir3pho3nixx Thank you for the help! It was unexpected to me that Winsor does not resolve a component by service type as interceptor when ComponentRegistration.Interceptors<TService>() is called. =)
