一種方式是託管 c++，但是有可能對程式碼更改較大，
另一種是連結

check out C++/CLI (aka managed C++). Write a wrapper that uses your native class as a member

最好給每一個用到的native concrete class 寫一個對應的Interface，在Managed C++ 裡用 INativeCore 而不是NativeCore ，來避免一些坑

// in your native core:

// define an interface wrapper for your native core
class INativeCore{
// ...
}
class NativeCore: public INativeCore{
// ... 
}

// in your C++/CLI code
ref public class ManagedClass{
private:
  INativeCore* pCore; // delegate all method calls to native core
public:
  void foo(){
  pCore->foo(); 
}
// ... other methods
}
