The Windows Phone SDK includes a tool for analyzing the capabilities required by your app. To analyze your app’s capability requirements, perform the following steps:
1. Build the app using a Release configuration.
2. Right-click the Windows Phone app project’s node in the Visual Studio Solution Explorer and select Open Store Test Kit (see Figure 2.2).
3. Click the Run Tests button to begin the analysis process.
The Capabilities Validation test that is present for Windows Phone 7.1 apps is not available for apps that target Windows Phone 8.
