Load SyndicationFeed and async/await

Question

Can we read RSS by async/await?

XmlReader reader = XmlReader.Create("http://localhost/feeds/serializedFeed.xml");
SyndicationFeed feed = SyndicationFeed.Load(reader);

Any clue?

Answer 1

Your solution is not using async/await, has too much code, and I suspect your approach is prone to deadlocks under certain scenarios.

Simply do this

var reader = XmlReader.Create("http://localhost/feeds/serializedFeed.xml");
var feed = await Task.Run(() => SyndicationFeed.Load(reader));

Ok folk, here is working solution

private  void   GetRSS(string rssUrl)
        {
            Task.Factory.StartNew(() => {
                using (XmlReader r = XmlReader.Create(rssUrl))
                {
                    SyndicationFeed feed = SyndicationFeed.Load(r);
                    Action bindData = () => {
                        lstFeedItems.ItemsSource = feed.Items;
                    };
                    this.Dispatcher.InvokeAsync(bindData);
                }
            });
        }
