We’re running a challenge where in you can Win a Nokia Windows Phone. The rules of said competition are detailed in the aforelinked post. There is just one week left after this, here is question 8, last one for the penultimate week.
Performance in mobile applications is paramount as users are on the go and don’t want to, nor will they, wait for your application. As part of the tools offered to Windows Phone developers, there are a number of features that can be used to tune application performance.
List, and describe how you would use, a feature of the Windows Phone developer tools that can be used to improve application performance. You can list other tools that are available to developers but they must be free for developers.
