Target Multiple Platforms in Native Device Projects
Using Visual Studio 2005 you can 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.
After you create your project. For more information, see.
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 need to manually add a platform and resource file. For more information, see.
