The Preview Tool is a Windows Media Center application that allows you to load MCML files and run them. This tool can also be used for certain types of debugging (such as syntax checking, focus and input checking, and UI region boundary indications). This tool is only supported on a computer running Windows Media Center.
The Preview Tool is registered as a Windows Media Center application, so you can run it within Windows Media Center (on the Windows Media Center Start page, go to
Extras >
Extras Library, and then select
Preview Tool).
You can also run the Preview Tool as a stand-alone application. The stand-alone version is useful for testing UI, but it cannot run code that depends on other Windows Media Center features or APIs. For example, you cannot view live TV from the stand-alone Preview Tool.
