如何打包一个针对通用Windows平台的多架构.NET库？

当然,缺失的部分是参考组件.值得庆幸的是,这很容易解决 - 引用程序集是一个AnyCPU程序集,它定义了运行时程序集包含的相同类和方法.它的主要目的是为编译器提供一个使用的引用,因此编译器可以验证所有方法调用实际上是引用将在运行时存在的方法.引用程序集中的实际代码(如果有)不用于任何内容.

由于所有特定于体系结构的构建都暴露了相同的API表面,因此我们可以简单地使用它们中的任何一个并指示编译器将其用作引用程序集.Windows SDK包含一个名为CorFlags.exe的实用程序,可用于将x86程序集转换为AnyCPU程序集,从而实现此目的.

下面是一个包创建脚本,它在打包库之前创建所需的引用程序集.它假定Windows SDK安装在标准位置.要了解逻辑的详细信息,请参阅内联注释.
