The OS Design Template

The OS Design Template

A CE 6.0 OS design template is a subset of the catalog components required to use Windows Embedded CE for a particular purpose. It is not necessary to start from a template when creating a new OS design, although it can save a significant amount of time to do so. It is straightforward to change catalog components later by selecting them in the Catalog Items View.

Choosing an appropriate template can save you development time and effort. For example, you might have to demonstrate the features of a new development board at a trade show. In this case, it is a good idea to start with the PDA Device or Consumer Media Device design template and add the required components and common Windows applications in the OS Design Wizard, such as the .NET Compact Framework 2.0, Internet Explorer®, and WordPad. On the other hand, if you are developing a driver for a Controller Area Network (CAN) controller, it might be better to start with the Small Footprint Device design template and only add what's absolutely necessary to minimize the size of the run-time image and to keep startup times at a minimum.

The OS Design Wizard is flexible and supports custom design templates. Template files are Extensible Markup Language (XML) documents, located in the %_WINCEROOT%PublicCEBaseCatalog folder. You can start with a copy of an existing Platform Builder Catalog XML (PBCXML) file and modify the PBCXML structures according to your specific needs. Platform Builder automatically enumeates all .pbcxml files in the Catalog folder when you start Visual Studio or refresh the Catalog Items View in Visual Studio.
