Instructs Windows Communication Foundation (WCF) to disable the mandatory processing of headers not in the UnderstoodHeaders collection that must be understood according to the SOAP 1.1 and 1.2 specifications.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
Thetype exposes the following members.
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|IEndpointBehavior.AddBindingParameters||Supports behavior functionality.|
|IEndpointBehavior.ApplyClientBehavior||Assigns the value of ValidateMustUnderstand to the ValidateMustUnderstand property.|
|IEndpointBehavior.ApplyDispatchBehavior||Assigns the value of ValidateMustUnderstand to the ValidateMustUnderstand property.|
|IEndpointBehavior.Validate||Supports behavior functionality.|
By default the WCF client or service runtime throws an exception when it encounters a System.ServiceModel.Channels.MessageHeader in a message for which the MessageHeader.MustUnderstand property is true but the header is not in the MessageHeaders.UnderstoodHeaders property for the message.
To prevent this behavior, use the and set the ValidateMustUnderstand property to false. Typically, this is used in scenarios where the message content is meant to be relayed somewhere else and not processed, such as a router service.
