I have a Metro app in C# & XAML. The tile is
updated periodically and I've used WebAPI to serve the tile notification XML. So far so good. I was then told that I cannot use WebAPI as the server that I was planning to host it on does not have .NET 4.5. No plans to install it anytime soon either. I had to change the WebAPI to a plain old Web service (.NET 3.5) which does the same thing - return tile notification XML. I've enabled HTTP-GET (I know, security concern) and was able to invoke the webservice like this -
http://server/TileNotifications.asmx/
[email protected]
But ever since I made the switch, the tiles are not being
updated. I've checked Fiddler and made sure the app is hitting the webservice and the XML is being returned correctly. But the tiles are not
updated. If I replace it with the WebAPI, the tiles are
updated.
Do I need to do anything special with the web services? like decorating the web method with a custom attribute? Here's my web service code -
[WebMethod]
public XmlDocument GetTileData(string user)
{
// snip
var xml = new XmlDocument();
xml.LoadXml(string.Format(@"<tile>
<visual>
<binding template='TileWideSmallImageAndText02'>
<image id='1' src='http://server/images/{0}_wide.png'/>
<text id='1'>Custom Field : {1}/text>
<text id='2'>Custom Field : {2}</text>
<text id='3'>Custom Field : {3}</text>
</binding>
<binding template='TileSquarePeekImageAndText01'>
<image id='1' src='http://server/images/{0}_square.png'/>
<text id='1'>Custom Field</text>
<text id='2'>{1}</text>
</binding>
</visual>
</tile>", value1, value2, value3, value4));
return xml;
}
