I'm trying to retrieve using Windows.Web.Syndication and a Blogger ATOM feed, the link of a post. The example I've seen from another feed reader (not using Blogger though) uses a SyndicationItem id to find the blog post link.
However, using this method, I get an Id in this format:
/tag:blogger.com,1999:blog-5388280093621795916.post-2321273013867491101
How can I access the original BlogPost URL using this?
