I’d like to stop immediately a method if I press cancel in the “processing” animation screen. I’m using Async call through delegates. Is it possible to stop immediately the execution of the method through delegates?
Thanks 🙂

No – at least, not cleanly. (I don’t include
Thread.Abortas “clean”.) What you should do is have a mechanism to tell the delegate that you’re trying to cancel it. Your delegate would then need to occasionally check that cancellation flag and react accordingly.Parallel Extensions has cancellation built into it all over the place (and in particular cancellation tokens to allow only appropriate pieces of code to cancel the task). It’s all still co-operative though, as far as I’m aware. Forced cancellation will always run the risk of corrupting state.
