I have a Windows Service which communicates with WCF services. The WCF services are all fault shielded and generate custom UserFaultContracts and ServiceFaultContracts. No problems there.
In the Windows Service I am using EntLib for exception handling and logging.
I do not want to try catch for faults
try
{
}
catch (FaultException<UserFaultContract>)
{
}
I want to use EntLib
try
{
}
catch (Exception ex)
{
var rethrow = ExceptionPolicy.HandleException(ex, "Transaction Policy");
if (rethrow) throw;
}
This also works, however, in my Tranasaction Policy I want to Log the details of the UserFaultContract. This is where I am unglued. And I hate becoming unglued. The fault is captured and logged...but I can't get the details of the fault.
My exception policy is
<add name="Transaction Policy">
<exceptionTypes>
<add type="
System.Exception, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"

The exception logged is:

Type :
System.ServiceModel.FaultException`1[[LCI.DispatchMaster.FaultContracts.ServiceFaultContract, LCI.DispatchMaster.FaultContracts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]],

Message : There was an internal fault at the DispatchMaster service.
Source : mscorlib
Help link :
Detail : LCI.DispatchMaster.FaultContracts.ServiceFaultContract
Action : http://LCI.DispatchMaster.LogicalChoices.com/ITruckMasterService/MergeScenarioServiceFaultContractFault
Code :
System.ServiceModel.FaultCode
Reason : There was an internal fault at the DispatchMaster service.
Data :
System.Collections.ListDictionaryInternal
TargetSite : Void HandleReturnMessage(System.Runtime.Remoting.Messaging.IMessage,
System.Runtime.Remoting.Messaging.IMessage)
Stack Trace :
In the fault contact there is an ID and a Message. I would, as you can see, like the ID and Message to be logged by EntLib.
I am assuming that I'm going to have to write a custom handler to exctract the fault details - but thought I'd ask if I'm missing something in EntLib which might help me avoid that task.
Thanks to anyone who is willing to help.
