c# 4.0 - C++/CLI Interface is not visible from my C# Class -


i have interface in c++/cli need implement in c#, not visible. have other classes (abstract , concrete can inherit from).

my c++/cli interface:

namespace mynamespace { namespace mysubnamespace {   public interface class itestinterface { public:     property bool firstproperty     {         bool get();     }      property bool secondproperty     {         bool get();     }  };  }}

i have test project use functionality in managed library, interface never becomes visible.

how try use in c# test project: (i tried using class library project also, , doesn't work either).

public class test: mynamespace.mysubnamespace.itestinterface {  }

i "cannot resolve symbol 'itestinterface'"

what missing?

update

i kept trying different things following comments question, , found if include .h file in other .h file of c++/cli project, class becomes visible. do:

#include "itestinterface.h"

in 1 of other .h files of c++/cli project , class becomes visible c# project.

is there way avoid doing that?

c++/cli similar c++ in .cpp files compiled directly. header files compiled when included. why adding #include interface header works.

there several ways make sure code included c++/cli class:

  • have both .h , .cpp file (even if .cpp file includes .h file corresponds to)
  • have include files , include of headers in 1 .cpp file (which may empty other includes)
  • have .cpp files (which fine if other code not reference code)
