I wrote a C# project in which I use a C++ dll (also written by me). I am trying to debug this dll function from my C# solution.
I have added C++ project to C# solution and manage its output – that’s ok. But I could not get into the dll functions (break points not loaded).
Assuming you are using a version of Visual Studio that is not Express, you should be able to allow native C++ debugging by checking an option in the properties pane of the project you are running. Go to Project Properties -> Debug -> Enable unmanaged code debugging.
