Windows 8 在Win8和WP8应用程序中共享静态库 我有一个C++语言编写的静态库，我希望能在.NET中编写Windows 8和Windows Phone 8应用程序。

我希望通过设置我的解决方案（如下所示），尽量减少要维护的独立项目的数量：

尝试#1：只有UI项目是特定于平台的

<强>问题：< /强>似乎可移植类库不支持以任何形式包含本机C++代码。

一种在Windows 8和Windows Phone 8应用程序中包含本地C++的方法是通过创建Windows运行时组件。不幸的是，针对Win8和Wp8的WRC项目是不同的项目类型；没有选项创建针对多个平台的Windows运行时组件

因此，为每个目标平台创建Windows运行时组件项目会产生以下结果：

尝试#2-UI项目是特定于平台的，LegacyLib包装器也是如此 问题：当我试图从LegacyWrc_Win8项目中引用LegacyLib时；我看到以下警告：

不建议添加对“LegacyLib”的引用，因为它与Windows应用商店应用程序不兼容

构建环境表示，要使LegacyLib静态库与我的Win8 Windows运行时组件兼容，我必须在LegacyLib项目配置中启用Windows应用商店应用程序支持（忽略警告只会导致以后出错）：

• 项目属性>配置属性>常规>项目默认值
• 将Windows应用商店应用程序支持设置为“是”

接下来，当我尝试对LegacyWrc_Wp8项目执行相同的操作时，我得到以下错误：

无法添加对“LegacyLib”的引用，因为这两个项目针对不同的平台

因此，使静态库与Windows 8兼容使其与Windows 8 Phone不兼容

看起来，即使库本身不包含特定于平台的代码，也不可能构建一个可供这两个不同平台使用的静态库

我不必维护源代码的并行版本，但我必须创建/维护两个独立的项目，每个项目都构建一个特定于平台的静态库版本

我的解决方案现在每个项目都有一个特定于平台的版本：

尝试#3-每个项目都是特定于平台的 问题：到目前为止，我看不到任何问题（除了这是一个丑陋且维护成本较高的事实）

顺便说一句，我确实研究了使用构建配置的可能性，但它们已经被用于调试/发布和x86/ARM的组合。将Win8/Wp8添加到混合中只会使配置再次翻倍，而且您已经改变了配置，而不是减少了维护负担。

我错过什么了吗？这似乎是一件很平常的事。是否有其他人经历过这一过程并提出了替代/更好的方法

编辑以确保完整性 这就是我最后做的

我意识到，LeaCyyApILB导出的几个辅助类可以用托管C++编写而不是用C语言编写。这意味着我可以将它们与WRC项目捆绑在一起，这简化了一些事情。

正如您所发现的，本机库需要为每个平台分别编译，因此不能直接从可移植类库中引用

我建议使用抽象模式，允许您通过可移植类库共享大部分.NET代码（即模型和视图模型）。在PCL中，为本机库中公开的功能创建接口或抽象类。然后在特定于平台的项目中实现这些功能，将调用转发到本机库。最后，使用依赖注入来连接这些接口的实现，以便您可以从共享PCL调用它们

以下是几篇关于这方面的博客文章：
