MessageInspector or Orperation Behavior

Question

User-221752185 posted

Trying to understand really when to the OperationBehavior. My scenario... The client needs to send a timestamp in a message header to my WCF. The WCF needs to validate that the timestamp is valid and no more than 30 mins out of bounds to the server time. Rather then checking and duplicating code on each operation, I'd rather just write it once. I was thinking to use OpertaionBehavior, but then MessageInspector looks at the message... Im a bit confused.

Timeout can be utilised to meet the requirement.

I would appreciate it if you could satisfy my question in regards to MessageInspector vs OperationBehavior. I need to have a better understanding of these too and why one would be a more appropriate solution.

MessageInspector

A message inspector is an extensibility object that can be used in the service model's client runtime and dispatch runtime programmatically or through configuration and that can inspect and alter messages after they are received or before they are sent. MSDN Reference

OperationBehavior

Specifies the local execution behavior of a service method. MSDN ref

The WCF needs to validate that the timestamp is valid and no more than 30 mins out of bounds to the server time.

As suggested above this can be achieved through Timeout property, which is configurable through Web.config

Could you use the OperationBehavior to do this? What is the difference between an OperationBehavior and a ContractBehavior?
