Async Execution Cancellation

[adiamante]

Hi would you be open to adding a cancellation token for async execution?

I'm looking for something like the following:

var context = new JSContext();
var cancellationTokenSource = new CancellationTokenSource();
await context.ExecuteAsync("code", cancellationTokenSource .Token);

// to stop execution/throw cancelled exception
cancellationTokenSource.Cancel();

@adiamante Currently not possible, but we are adding AbortController and you will be able to pass CancellationToken as AbortController which can be used internally to pause some of async operations. However, the issue is currently in CLR, we have no way of pausing execution of IL instructions so code will not stop execution. But any IO utilizing cancellation token will throw an exception which will then throw AbortError inside JavaScript.

@ackava Understood. Thank you for the reply
