Target Multiple Platforms in Native Device Projects
Visual Studio enables you to create a single device project that targets multiple device platforms, such as Pocket PC 2003 and Smartphone 2003.
There are two ways that you can set your device project to target multiple platforms:
With the application wizards at the time of project creation.
This is the easier method. For more information, see How to: Using the Wizard to Create a Multiplatform Device Project.
After you create your project.
For more information, see How to: Add a New Platform to a Device Project.
If you select multiple platforms on the Platforms page in the application wizard of your project, a resource file will be generated and configured for each of your platforms. However, if you add a platform after you create your project, you will have to manually add a platform and resource file. For more information, see Using Resources on Multiple Platforms.
