Live Tile Update base on Periodic and Normal web Service

Question

Hi , I need to update the live tile periodically every 30 minutes. The data is from web service.

1) I use a WebClient to get the data from a server

2) when data return, I create a XML file with the Data.  Say , the return data is:   weather.

 string strXML =     "  <tile> " 
                            + " <visual>"
                            + "<binding template="  + "TileSquareText04" + ">"

                            +"<text id=" + "1"  + ">Weather </text>"

                            + " </binding>"
                             + "  </visual>"
                             + " </tile>"

How and where to get the WebClient to start downloading?

How to I use the TileUpdater to update the tile base on the XML template above?

The above XML template is  one of the 46 XML templates.  Please kindly provide me a working sample. 

Thanks

Hi FireDance,

>>How and where to get the WebClient to start downloading?

Unfortunately, there is no WebClient class in runtime, I would suggest you using HttpClient class to sends HTTP requests and receive HTTP responses.

Check the official sample for details: https://code.msdn.microsoft.com/windowsapps/HttpClient-sample-55700664

I would recommend you to use a background task to update your app's live tile, please refer to this article about how to update a live tile from a background task: https://msdn.microsoft.com/en-us/library/windows/apps/xaml/jj991805.aspx?f=255&MSPPError=-2147217396
