Fails reading Google Bookmarks RSS using .NET

问题

Hi I am experiencing weird problem. I want to consume Google Bookmarks RSS in my .NET application. Here is the code:

string rssUrl = "https://www.google.com/bookmarks/?output=rss";
NetworkCredential credentials = new NetworkCredential("myusername", "mypassword");
XmlUrlResolver resolver = new XmlUrlResolver { Credentials = credentials };
XmlReaderSettings settings = new XmlReaderSettings { XmlResolver = resolver };
XmlReader reader = XmlReader.Create(rssUrl, settings);
XDocument document1 = XDocument.Load(reader); // Fails here

When I open rssUrl in browser I see all my bookmarks as RSS feed prefectly. When I run this code, it fails. In fact, what is returned back is the Google SignOn page instead of the RSS.

Using exactly the same code I can read Gmail RSS no problem.

But not Google Bookmarks RSS. This doesn't make any sense to me. It should be straight forward and very simple.

Please advice. Thanks a bunch.
