The Application Deployment Tool

XAP files allow you to circulate your app to developers that have a developer unlocked device. This is done using the Application Deployment tool that is installed along with the Windows Phone SDK. The tool allows you to navigate to select a XAP file and deploy it to a connected phone device (see Figure 2.1).
