您感到困惑两件不同的事;内核开发和应用程序开发。

You are confusing two different things; kernel development and application development.

内核开发：用于Windows CE 6.0的Platform Builder R3是VS2005的插件，在VS2008中不起作用

Kernel development: Platform Builder for Windows CE 6.0 R3 is a plugin for VS2005 and does not work in VS2008

内核开发：用于Windows Embedded Compact 7的Platform Builder是VS2008的插件，在VS2005（或VS2010）中不起作用

Kernel development: Platform Builder for Windows Embedded Compact 7 is a plugin for VS2008 and does not work in VS2005 (or VS2010)

应用程序开发：使用从PB生成的SDK for CE 6.0 - 或 - 从VS为WEC7生成的SDK可以在VS2008中使用，没问题。

Application development: Using an SDK generated from PB for CE 6.0 -or- an SDK generated from PB for WEC7 can be used in VS2008, no problem.

根据您在应用程序中使用的SDK功能，您可能需要针对您的OS设计重新编译WEC7 SDK一旦你切换。

Depending on the SDK features you use in your application you may need to recompile against the WEC7 SDK for your OS Design once you switch.

希望这有助于清除迷雾......

Hope this helps clearing the fog...
