How to specify only certain FaultExceptions to be Passed?

Question

I have a WCF service and there is a CustomFaultException class inheriting from FaultException.

I have set the below code:

<serviceDebug includeExceptionDetailInFaults="False"/>

But it always returns the Exception with full stack trace details.

How to configure or implement a WCF Service so that only returns certain types of Exceptions e.g. CustomFaultException?

Thanks

Add the following attribute to your Service Operation:

[FaultContract(typeof(CustomFaultException))]

Within your catch, add the following:

throw new CustomFaultException("Custom Fault Message");

This will prevent the full stack trace exception details from being sent to the client.
