Tile notifications are specified in an XML format and contain text and images in a pre-defined layout.
Applications must always include a medium (Square150x150) logo in the
manifest. Similarly, if an application wants to use wide (Wide310x150)
tile templates, it must include a wide (Wide310x150) logo with it as
well. Applications that want to use large (Square310x310) tile
templates must include both Wide310x150 and Square310x310 logos.
On Windows 8.1, each application automatically supports the small
(Square70x70) tile size by simply shrinking down the Square150x150 logo.
An application can override this logo in the manifest if it so chooses.
On Windows Phone 8.1, each application is required to provide small
(Square71x71) logo. When sending live tile notifications, it is
strongly recommended to send bindings for all supported tile sizes in
each payload since users decide what size your application's tile will
be. Note that only Windows Phone 8.1 makes use of a binding for the small
tile size. This size does not support live tile
updates on Windows 8.1 (but does support badge updates).
Given below are two different use cases. Before you send the notifications, make sure that you pin the tile to your Start screen.
Once you send the notification, check how the pinned tile shows those updates.
