Can we read RSS by async/await?
XmlReader reader = XmlReader.Create("http://localhost/feeds/serializedFeed.xml");
SyndicationFeed feed = SyndicationFeed.Load(reader);
Any clue?
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));
