Windows Phone Capability Detection Tool
Detects the phone capabilities used by your application. When you submit your application to Windows Phone Marketplace, Microsoft performs a code analysis to detect the phone capabilities required by your application and then replaces the list of capabilities in the application manifest with the result of this detection process. This tool performs the same detection process and allows you to test your application using the same list of phone capabilities generated during the certification process. For more information, see How to: Use the Capability Detection Tool.
Windows Phone Connect Tool
Allows you to connect your phone to a PC when Zune® software is not running and debug applications that use media APIs. For more information, see How to: Use the Connect Tool.
