Ok so this is a very simple Silverlight 2 voting control that I worked on to learn how to do a few things in Silverlight.  I will be making a Silverlight 3 version once it is officially released.  I guess some would call this a silverlight polling control as well.  I don't know, I'm calling it a voting control.  So here is what it was designed in:

• Silverlight 2.0
• ASP.NET 3.5 site hosting the Silverlight control
• Visual Studio 2008

Here are the concepts involved in the control:

• Read an XML file via the WebClient using the OpenReadAsync method
• Write an XML file via the WebClient using the UploadStringAsync method
• LINQ to XML
• The Charting Control using the Bar Series.

Here are some notes about the control.

• It is not very fancy so please style it how you please.  I personally took out the legend on the BarSeries because it allows for more room.  
• It does not have any sort of management interface to edit the XML file.
• Give the PollData directory in the Web Project write access
• fileUploader.ashx in the Web Project handles writing the file back to PollData (could use some more error catching
• Dimensions are 350 x 345
• FileUri and FileUploaderUri paths are in the App.xaml
• The XML file contains the question and title as part of the root attributes

Here are some screenshots of what it looks like
