System.Object
  System.ServiceModel.Description.CallbackDebugBehavior

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

public class CallbackDebugBehavior : IEndpointBehavior

The CallbackDebugBehavior type exposes the following members.

  NameDescription
Public methodCallbackDebugBehaviorInitializes a new instance of the CallbackDebugBehavior class.
Top

  NameDescription
Public propertyIncludeExceptionDetailInFaultsGets or sets a value that controls whether client callback objects return managed exception information in SOAP faults back to the service.

  NameDescription
Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Set the IncludeExceptionDetailInFaults property to true from an application configuration file or programmatically to enable the flow of managed exception information in a client callback object back to the service for debugging purposes.

Caution noteCaution

Returning managed exception information to services can be a security risk because exception details expose information about the internal client implementation that could be used by unauthorized services. In addition, although the CallbackDebugBehavior 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.

For more information about the security issues related to managed exception information, see Specifying and Handling Faults in Contracts and Services.

You can also set the values of this attribute by using the <callbackDebug> element in a client application configuration file.

The following code example shows a client configuration file that instructs WCF to return managed exception information from a client callback object in SOAP messages.
