Question from the WCF test

Generate a proxy class with asynchronous methods and use it for new clients.

Medium

A WCF service exposes the following contract over the HTTP protocol (code below).
Existing clients make blocking calls to the GetData method. The GetData method takes up to 5 seconds to execute.

You need to ensure that new clients can send non-blocking requests to this method, without modifying existing clients. What should you do?
