What's the best way to cancel an asynchronous WCF request?

Question

(Assuming a WCF method called \"MyFunction\")

Currently, to support canceling a WCF request, I\'m using the BeginMyFunction/EndMyFunction methods generated by svcuti

Answer 1

Easiest way I know of to do this with a WCF Client and the Task based async pattern is to register an Abort action with the cancellation token

private async Task CallOrAbortMyServiceAsync(CancellationToken cancellation)
{
    var client = new SomeServiceClient();
    cancellation.Register(() => client.Abort());
    try
    {
         await client.CallMyServiceAsync();
    } catch (CommunicationObjectAbortedException) {
          // This will be called when you are cancelled, or some other fault.
    }
}
