title: Best Practices to Deprecate WCF Services
body: <p>Is there any attibute or similar mechanism to inform a web service consumer that a Service/Operation contract has been deprecated?  I have a set of WCF services that need updating.  As part of this update I would like to simplify some of the original design.  I plan on leaving the existing operations in place but I would like to somehow inform the end users that they have been deprecated in favor of the new operation/service.  What are the best practices for accomplishing this?</p>
