WCF And Debugging Exceptions

A common problem in WCF is to receive the exceptions on client when debugging.
The WCF behaviors configuration allows this using the includeExceptionDetailInFaults, but to receive the inner expection the returnUnknownExceptionsAsFaults must also be set to true.
The maxItemsInObjectGraph is only to avoid the error of exceeding the maximum number of items that can be serialized or deserialized.

        <behavior name="MyServiceBehavior" returnUnknownExceptionsAsFaults="True">          
            <serviceDebug includeExceptionDetailInFaults="true" />
            <dataContractSerializer maxItemsInObjectGraph="2147483647" />
