A RSS feed aggregator aggregates syndicated web content such as online newspapers, blogs, podcasts, and video blogs (vlogs) for various purposes e.g. to provide one location for easy viewing.
The VB module provides a code sample for one way you can create a RSS feed aggregator with VisualBasic.
Module Module1 Const feedUrl As String = "http://+:8086/VBfeeds/" Sub Main() Dim listener As New HttpListener listener.Prefixes.Add(feedUrl) listener.Start() 'Open a browser pointing at the feeds being served. System.Diagnostics.Process.Start("iexplore.exe", "http://localhost:8086/VBfeeds/") 'Serve requests. While True Dim context As HttpListenerContext = listener.GetContext() Dim body As XElement = GetReplyBody() context.Response.ContentType = "text/xml" Using writer As XmlWriter = New XmlTextWriter(context.Response.OutputStream, System.Text.Encoding.UTF8) body.WriteTo(writer) End Using End While End Sub Function GetReplyBody() As XElement Dim feeds() As String = {"http://blogs.msdn.com/vbteam/rss.aspx?Tags=VB6_5F00_Migration_2F00_ "http://blogs.msdn.com/vsdata/rss.xml", _ "http://blogs.msdn.com/vbteam/rss.aspx?Tags=IDE&AndTags=1"} Return VB Genius http://+:8086/VBfeeds/ VB Team Members XLinq-based RSS aggregator using VB Only Super Cool XML Literals Feature End Function End Module

Windows 8.1 includes the new Back button control. The BackButton provides a way for you to add backward navigation to your app.
<button data-win-control="WinJS.UI.BackButton" >button>
You don't have to write any code. The BackButton automatically checks the navigation stack to determine whether the user can navigate backwards. If there is nothing to navigate back to, the button disables itself. When the user clicks the button or uses keyboard shortcuts (such as Alt+Left or the BrowserBack keys), it automatically calls the WinJS.Navigation.back function to navigate backwards.
