W8 Phone System.Xml.XmlException with XmlReader

I am trying to make a RSS app for Windows Phone 8 but there is an error occurring whenever I try to download the RSS content using a XmlReader.

using System.Xml.Linq;
using System.Net;
using System.ServiceModel.Syndication;

XmlReaderSettings settings = new XmlReaderSettings();
                settings.DtdProcessing = DtdProcessing.Ignore;

                XmlReader reader = XmlReader.Create(http://ift.tt/1mc7dVz, settings);
                SyndicationFeed feed = SyndicationFeed.Load(reader);
                reader.Close();

The error is found on the line "XmlReader reader = XmlReader.Create...." The full error message is:

A first chance exception of type 'System.Xml.XmlException' occurred in System.Xml.ni.dll

Additional information: Cannot open 'http://ift.tt/1mc7dVz'. The Uri parameter must be a file system relative path.

Thank you for your help! :)
