LNK2022 (Duplicate managed types have different visibilities) on MSVS 2012

Question

I\'m porting a solution from MSVS2005 to MSVS2012. The projects are in C++ .NET but use homemade native C++ libraires too. We had no problem building the projects with 2005

Answer 1

Had the same issue upgrading from VS2008 to VS2012. An alternative solution to the hotfix for me was to move the

#pragma make_public( ClassName )

statement from the .cpp file where it was up to now to stdafx.h.
