Linking liberary with CLR

Hi, For a small project of mine I tried to link your library to a C# project. This failed due to the fact that your library is unmanaged, so I tried creating a C++/CLR wrapper to do this, but I kept failing. Now isn't C++/CLR really in my comfort zone and even though I created a .lib file out of your .def file the compiler didn't seem to pick up the .dll itself and I have no clue how to do it. Does anyone have any experience in linking C++/CLR to this libdivecomputer? Or even better, with C#? Kind regards, Vincent
