Use in solution with VC++ project

Hi,

My solution contains one VC++ project that builds a DLL which is used by my test assembly. This unmanaged DLL is required to run the tests (basically, my .NET assembly will be testing against the unmanaged version).

Now when I configure NCrunch in my solution it will try to build the VC++ project and, as far as I can see, will try to load the unmanaged DLL as if it were managed, giving me an error:

NCrunch: If you are experiencing problems in getting this project to build, have a look at https://www.ncrunch.net/documentation/troubleshooting_project-build-issues

Is there any way to workaround this?

Thanks

Hi Pedro,

At the moment NCrunch doesn't support C++ projects. The best workaround I can offer would be to avoid creating project references to C++ projects inside your solution - use assembly references instead. Using the IDE, delete all references from other projects in your solution to your C++ project, then replace them with references to the compiled C++ assembly on disk. If you adjust your NCrunch project configuration to enable the 'Ignore this component completely' on the C++ project, NCrunch should be able to build and run tests over your solution while ignoring the C++ project.

This suggestion is theoretical since without your solution I have no way to be sure whether it would work, but my expectation is that NCrunch won't trigger for any changes you make to your C++ project until you manually rebuild it.

I'm keen to hear if this gets you working.


Cheers,

Remco
