This is a repost from the Windows Phone Developer Blog. It’s great news for those waiting for the WP 7.8 release as well as developers interested in sprucing up their apps to take advantage of the new functionality, such as Live Tile resizing and such. Here is the original post.
“Today we are releasing the Windows Phone SDK Update for Windows Phone 7.8, an optional update that adds two new Windows Phone 7.8 emulator images to your existing SDK installation. These two emulator images should enable you to fully test how your Windows Phone 7.5 app’s Live Tiles will look and behave when they are run on a device running Windows Phone 7.8. New phones with Windows Phone 7.8 are beginning to ship, so it’s a great time to update your apps to take advantage of the new Live Tile experience and to reach the new markets that Windows Phone 7.8 makes available.
This blog post briefly covers what is included in the Windows Phone SDK update; I’d highly recommend that developers take a look at Thomas Fennel’s blog on how to ‘light up’ your 7.5 app in Windows Phone 7.8 and 8.0 for a technical overview of how to use the new emulator images.”
