Developing a Windows Mobile Device Application Using Visual Studio

After you import Unwired WorkSpace projects (mobile application or Device Application Designer) and associated libraries into the development environment, use the Client Object API, Windows Device Framework, and native APIs to create or customize your device applications.

Note: Do not modify generated MBO API or Device Application Designer generated code directly. For Device Application Designer Code, use the customization pattern documented in this guide by either adding event handlers or customization classes. For MBO generated code, create a layer on top of the MBOs using patterns native to the mobile operating system development to extend and add functionality.
