You can add Windows Phone 8 apps to Device Manager and make them available to your users. You can deploy apps to devices using a deployment package.
Makes sure that before you deploy apps to your users, that the app has been signed by the Microsoft app signing tool (XapSignTool.exe) with a valid app certificate. For more information, see Configuring Apps for Windows Phone 8 Worx Home
You can add Windows Phone 8 apps in two ways:
- Internally. Upload the application to the Device Manager database as an Windows .xap file
- Externally. Create an application definition that references the App data through a URL to the Windows Phone app store.
