Isolation-mode (regfree) COM references defined twice (build error MSB3180)

Question

I have several C# projects in one solution which reference some isolation-mode (regfree) COM DLLs. Some projects reference the same DLL, and when I build, I get error [MSB3180][1]: COM component 'SomeDll.dll' is defined in both 'Native.SomeProject.manifest' and 'Native.SomeOtherProject.manifest'".

The projects must reference the same COM DLL, since they both use it, and both are completely independent of one another. It gets more complicated since I want to support non-isolation mode for Debug builds.

Any ideas or suggestions?

Answer 1

All those projects could reference a new DLL that acts as a wrapper to the singular DLL that references the Reg-Free COM.
