How to make a WCF client ignore the response?

Question

I have a contract in the same signature as an Action<T> delegate:

[ServiceContract()]
interface ISomeService
{
    [OperationContract()]
    void DoSomething(object data);
}

1. Will the client wait for the server side method execution to finish?
2. If yes, how to prevent this?
3. Should I use async calls to achieve my goal?

Answer 1

Look into one way operations.
