【C++/CLI】
A C++/CLI application or component uses extensions to C++ syntax (as allowed by the C++ Specification) to enable interaction between .NET and native C++code.
C++/CLI 是扩展了语法的 C++，使得 .NET和 C++代码可以交互。
A C++/CLI application can have parts that run natively and parts that run on the .NET Framework with access to the .NET Base Class Library.
C++/CLI 应用可以部分跑在本地，部分跑在 .NET框架上。
C++/CLI is the preferred option when you have native C++ code that needs to work with code written in C# or Visual Basic. It is primarily intended for use in .NET DLLs rather than in user interface code.
在有C++代码需要与 C# 混用的情况下，C++/CLI是优先选择。
