ServiceDebugBehavior.IncludeExceptionDetailInFaults Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets or sets a value that specifies whether to include managed exception information in the detail of SOAP faults returned to the client for debugging purposes.

Namespace:   System.ServiceModel.Description
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

public bool IncludeExceptionDetailInFaults { get; set; }

Property Value

Type: System.Boolean

true if Windows Communication Foundation (WCF) returns managed exception information in the SOAP faults for client debugging purposes; otherwise, false. The default is false.

Set the IncludeExceptionDetailInFaults property to true to instruct WCF to return managed exception information to the client in SOAP faults to ease debugging.


Returning managed exception information to clients can be a security risk because exception details expose information about the internal service implementation that could be used by unauthorized clients. In addition, although the ServiceDebugBehavior properties can also be set programmatically, it can be easy to forget to disable IncludeExceptionDetailInFaults when deploying.

Because of the security issues involved, it is strongly recommended that:

  • You use an application configuration file to set the value of the IncludeExceptionDetailInFaults property to true.

  • You only do so only in controlled debugging scenarios.

The following code example shows how to use a configuration file to enable the HTML help page feature and return exception information inside a SOAP fault back to the client for debugging purposes. This configuration file shows the following basic steps to adding support for the ServiceDebugBehavior features:
