What are the steps to get Wide Tiles working on WP7.8?

Question

I'm trying to get Application (default tile) wide tiles working in the 7.8 emulator, so far Ive
- I've followed the advice in this article Adding Wide Tiles to WP7.8.
- I added the extra element to the app manifest
- I can see my reflection code executes correctly to update the live tile. - This is on the 7.8 emulator

However when I try to resize the tile to the wide size I only get the small and medium options in the Emulator UI.
Is there anything I've missed?

Answer 1

Remote tile images was the issue. I've worked around this as follows

1. On first App Startup set the tiles to placeholder local images (set a flag in settings to indicate the tile is setup)
2. Set the App tile to the remote images as normal after this

This seems to work fine, I found it mentioned on one of the documentation pages I read for the 10th time last night.
