I have build a c# class library “verification.dll” using OpenCVSharp.
This references OpenCvSharp.dll in Solutiondir/Dependencies/ and has copylocal = true.

The Folder “Dependencies” has 4 files OpenCvSharp.dll, opencv_core230.dll, opencv_imgproc230.dll, tbb.dll, because OpenCvSharp requires these.

Now I have made a console program “ConsoleTest” to test the functionality of the class library, and this is where the problems begin.
I have to manually place the 3 files: opencv_core230.dll, opencv_imgproc230.dll, tbb.dl in Solutiondir/ConsoleTest/bin/x86/Release/.

I don’t want to do this. I want it to be possible to just reference verification.dll from the ConsoleTest, and then it just works.

How can I achieve this??

    I simply dragged the DLL’s from the folder to the project. Not as references, but as files. Set Build action: None, Copy to Output Directory: Copy if newer
