How to download an xml file by using .NET 4.0 C# and Silverlight( the IDE is VS2010)?

Hello Kirupa,

please read my message. I follo your tutorial, and I never have any problem; however, this time, I was not able to see some result of your tutorial on “How to download an XML file in Silverlight?”—
http://www.kirupa.com/blend_silverlight/loading_xml_sl2_pg1.htm

I am using Visual Studio 2010
and .NET 4 with C#.
The tutorial is at:
http://www.kirupa.com/blend_silverlight/loading_xml_sl2_pg1.htm
I cannot see the downloaded content of the xml file in the messagebox or in the HtmlPage.Window.Alert(xmlData);

I am trying to make a rss feed by using silverlight. My rss feed is from:

http://rss.msnbc.msn.com/id/3032127/device/rss/rss.xml

which has some image and the images are not part of the itemCollection; therefore, I believe that I need to download the whole xml file as a string to process, but I cannot download the xml file as I cannot see anything in message box or in the HtmlPage.Window.Alert(…);

I have also downloaded your tutorial zip folder and after I have pressed F5, as you have suggested in the second page, nothing happens.

Please tell me how to download a remote xml file as a string by using .NET 4.0 C#, where the IDE is VS 2010, in a Silverlight application.
