Using OpenCV from .NET C++/CLI

I am happy to report that I have had a reasonably easy run of using OpenCV from a .NET C++/CLI project, I was initially worried that the two might not play well together, but so far – so good! I am wrapping some machine vision code that uses OpenCV in a C++/CLI assembly so that I can call it from C# code. I have kept the rather creepy CLI stuff to a minimum it just implements the interface, everything else is vanilla C++ using the standard library.

 

The only thing I had to do to get rid of build errors was to make sure that each _proper_ C++ file in the project had the following value for the ‘Common Language RunTime Support’ build setting -> ‘No Common Language RunTime Support’!

 

So if you are toying with the idea of developing some OpenCV based software from within C++/CLI, I say give it twirl it makes interacting with .NET much easier than (say) using COM or similar!
