I have a problem configuring a ServiceBehavior for my WCF service.
Some background.
Basically I am developing a REST service WCF that is supposed to run on IIS.
I need to be able to log exceptions thrown by the service (I'm using log4net) and return HTTP status codes depending on the type of exception.
I want my service implementation to have a minimum knowledge of WCF related stuff, so I don't want to convert the exceptions to FaultException everywhere in the service.
So I figured out that adding my own IErrorHandler to the service host would be the best way to do it.
My problem is however that no matter what I try I can't seem to get the configuration for my custom ServiceBehavior right in Web.config.
Here is the relevant code.
Web config.
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<add name="UrlRoutingModule" type="System.Web.Routing.UrlRoutingModule, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</modules>
</system.webServer>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="UsingErrorLogBehavior">
<errorLogBehavior/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior>
<webHttp/>
</behavior>
</endpointBehaviors>
</behaviors>
<extensions>
<behaviorExtensions>
<add name="errorLogBehavior"
type="MyNameSpace.Web.ErrorExtensionElement, MyNameSpace.Web"/>
</behaviorExtensions>
</extensions>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>
<standardEndpoints>
<webHttpEndpoint>
<standardEndpoint name="" helpEnabled="true"
automaticFormatSelectionEnabled="false"
defaultOutgoingResponseFormat="Json"
maxReceivedMessageSize="4194304" transferMode="Buffered" />
</webHttpEndpoint>
</standardEndpoints>
</system.serviceModel>
ErrorExtensionElement.
namespace MyNameSpace.Web
{
public class ErrorExtensionElement : BehaviorExtensionElement
{
public override Type BehaviorType
{
get { return typeof(ErrorServiceBehavior); }
}
protected override object CreateBehavior()
{
return new ErrorServiceBehavior();
}
}
}
ErrorServiceBehavior.
namespace MyNameSpace.Web
{
public class ErrorServiceBehavior : IServiceBehavior
{
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)
{
channelDispatcher.ErrorHandlers.Add(new ExceptionModule());
}
}
public void Validate(ServiceDescription serviceDescription, System.ServiceModel.ServiceHostBase serviceHostBase)
{
}
}
}
Where ExceptionModule implements IErrorHandler.
