The following sections contain details about known issues in the Windows Phone SDK Update for Windows Phone 7.8.

Windows Phone Emulator

  • After installing either the Windows Phone SDK 7.1 or the Windows Phone SDK 7.1.1 Update, followed by installing the Windows Phone SDK Update for Windows Phone 7.8, selecting to repair the Windows Phone SDK 7.1 will result in the removal of the Windows Phone 7.8 emulator from the list of available emulators displayed in Visual Studio 2012. Alternatively, if the Windows Phone SDK 7.1.1 Update is installed after the Windows Phone SDK Update for Windows Phone 7.8 is installed, the Windows Phone 7.8 emulator will be removed from the list of available emulators displayed in Visual Studio 2012.

    User impact: The Windows Phone 7.8 emulator will not be listed as an available emulator in Visual Studio 2012.

    Workaround: If you need to repair the Windows Phone SDK 7.1 or the Windows Phone SDK 7.1.1 Update, do the following:

    1. Open command prompt.

    2. Run the following command:

      rd /s /q %LOCALAPPDATA%\Microsoft\Phone Tools\CoreCon\10.0

Tiles

  • When using flip or cycle Tiles, the Tile count is displayed in a square shape, rather than circle.

    User impact: Users will see the Tile count in a square shape, rather than a circle. Developers may have created the Tile UI assuming a Tile circle shape, and hence deliver a different experience. Users may get confused by a different shape than what they’ll see in Windows Phone 8.

    Workaround: Implement your own circular counter icon as part of their Tile UI.
