Best workaround for compiler error C2158: make_public does not support native template types

by

I’m not aware of any way to export that type. If you have to have that function signature, I would lean in the direction of using a mix of managed and native exports (managed functions using native types can’t be consumed by other languages anyway), and maybe use delay loading when calling the native exports so you have a chance to trap errors finding the assembly in the usual .NET way.

But your particular function may be problematic since it uses both managed types and complex native types in the signature.

In general, the best practice is to not pass native C++ classes across DLL boundaries at all, since this sets you up for One Definition Rule violations.

For this particular situation, my suggestion is to make an wrapper that implements ICollection. That cures the problem just like your solution #2, without ever having to actually copy all the elements into a new data structure.
