Using managed C++ dll from C#

Question

I've created a dll using managed C++. Now I'm trying to use it from C#. I've added the Object to project references. Object browser shows the object in the dll correcly, path to the dll in object browser corresponds to the actual path.

However, when I run the C# program it complains:

Unhandled Exception: System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Any idea what else have to be done?

Thanks.

Answer 1

I think that you're missing the other assemblies or dll's references by your managed C++ assembly.

Answer 2

Does your managed C++ assembly have an other dependencies, including unmanaged dlls? You'll see this error at runtime if your referenced assembly fails to load a dependency.

Answer 3

Are you running the application in release on a machine without VS installed?

I only ask because I ran into a similar problem here: http://stackoverflow.com/questions/230715/mixed-mode-library-and-crt-dependencies-help
