将 DLL 中的 unmanaged/native C++/CLI class 获取到 Visual Studio 2013 中的非托管单元测试
Getting unmanaged/native C++/CLI class in a DLL into a unmanaged unit test in Visual Studio 2013
在这里，我正在用头撞同一堵墙，所以我要问这个问题，要么得到答案，要么自己回答，这样我就可以在下一个[=43] =] 时间.
我的示例是使用内置模板从头开始创建的。我正在使用 MS 说明 "Unit testing native code with Test Explorer"
首先，我使用模板创建了一个非托管 DLL。这给了我：
