在开发过程中，您应该只针对一个 CPU(取决于您将在哪台机器上进行测试/调试).当需要发布您的应用程序时，您可以选择多个包，每个 CPU 架构一个.然后，Visual Studio 将创建多个包，您可以将它们上传到开发门户.

You should target just one CPU during development (depending on what machine you will be testing/debugging on). When it's time to publish your app, you can select multiple packages, one for each CPU architecture. Visual Studio will then create several packages, which you can upload to the dev portal.
