These slide are from the lab that explores the features of the Nokia Music Windows Phone API and show you how to install and use the API. Steve Robbins, Chief Architect for Nokia Music, describes how to code with the API to quickly add music features to existing apps, and demonstrates how to get music content into your app.
It is recommended that you install the Microsoft Windows Phone SDK 8.0 to get the most out of this training lab. Also, it will be helpful to have a Nokia Lumia phone built on Windows Phone 8 available for testing.
