How To Make WCF routing service log message to SQL server - wcf

Question

I'm trying to use Routing Service (http://msdn.microsoft.com/en-us/library/ee517422.aspx) to route the data from clients to other end points. I have multiple clients and the end point which is called from routing service is located at a third party.
I also need to Log every transaction passed through routing service into SQL Database.
The problem is I can't write custom code in routing service as it's working from configuration files. Given that I can't write custom code in these classes, how can I achieve this?

Answer 1

1) create a class library and sign it with strong key.
2)create RoutingServiceBehavior class this class will implement IServiceBehavior, IDispatchMessageInspector interfaces, the code for message interception will be in this class:
using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;
namespace Services.RoutingServiceBehavior
{
public class RoutingServiceBehavior : IServiceBehavior, IDispatchMessageInspector
{
public object AfterReceiveRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel, System.ServiceModel.InstanceContext instanceContext)
{
// This is your envelop
string s = request.ToString();
return null;
}
public void BeforeSendReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
{
}
public void AddBindingParameters(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase, System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints, System.ServiceModel.Channels.BindingParameterCollection bindingParameters)
{
}
public void ApplyDispatchBehavior(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
{
foreach (ChannelDispatcher channelDispatcher in serviceHostBase.ChannelDispatchers)
{
foreach (EndpointDispatcher endpointDispatcher in channelDispatcher.Endpoints)
{
endpointDispatcher.DispatchRuntime.MessageInspectors.Add(this);
}
}
}
public void Validate(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
{
}
}
}
3) Create RoutingServiceBehaviorElement class, this class will implement BehaviorExtensionElement interface:
using System;
using System.ServiceModel.Configuration;
namespace Services.RoutingServiceBehavior
{
public class RoutingServiceBehaviorElement : BehaviorExtensionElement
{
public override Type BehaviorType
{
get { return typeof(RoutingServiceBehavior); }
}
protected override object CreateBehavior()
{
return new RoutingServiceBehavior();
}
}
}
4)Build your project.
5)Add your assembly to GAC.
6)Open machine.config and add the name of your assembly under <behaviorExtensions> it shall look like that:
<add name="RoutingServiceBehavior" type="Services.RoutingServiceBehavior.RoutingServiceBehaviorElement, Services.RoutingServiceBehavior, Version=1.0.0.0, Culture=neutral" />
7) add the name of your service behavior in your wcf service under <serviceDebug>
<RoutingServiceBehavior/>
8)Make sure that the assembly dlls are included in your WCF service.
