Observable.FromAsync is it the right choice?

Saturday, March 22, 2014

Observable.FromAsync is it the right choice? one of the most common RX's practice is to use Observable.FromAsync for executing asynchronous IO operations. typical code may look like: Code Snippet var webClient = new WebClient(); IObservable<string> uris = ...; var dataStream = from uri in uris                     from data in Observable.FromAsync(                         () => webClient.DownloadDataTaskAsync(uri))                     select data; behind the scenes RX set a Task continuation (ContinueWith) and propagate the result through AsyncSubject, actually it is a bit complex and messy implementation combination with TPL Dataflow (.NET 4.5) may offer better solution to asynchronous...
