My live tile on the Start screen didn't work so I tried making it simpler and simpler to isolate the problem. I eventually got back to what is shown below, and it still doesn't work. It doesn't change the existing tile. Can anyone see why?
doc1 is an XMLDocument and doc1.GetXml() gives me this:
<image id="1" src="http://i.s-microsoft.com/global/ImageStore/PublishingImages/FY13/Asset/highlights/Store_1127_420x210_EN_US.jpg" alt="not found"/>
Then I have these two lines of code:
TileNotification tileNotification = new TileNotification(doc1);
Nothing seems to happen when this code runs.
I have InternetClient turned on in Package.appxmanifesrt.
The only thing I could get to work was a tile with no image.
Can was absolutely correct. I had chosen a template for a wide tile and was trying using it with start screen set up for a small tile.
I am taking a few days off work to try to get a proof-of-concept working for each critical piece of the app and I spent a long time spinning my tires on this.
Thank you very much Can.
