Linker Tools Error LNK2028

"exported_function" (decorated_name) referenced in function "function_containing_function_call" (decorated_name)

Remarks

When attempting to import a native function into a pure image, remember that the implicit calling conventions differ between native and pure compilations.

The /clr:pure compiler option is deprecated in Visual Studio 2015 and unsupported in Visual Studio 2017.

Examples

This code example generates a component with an exported, native, function whose calling convention is implicitly __cdecl.

// LNK2028.cpp
// compile with: /LD
__declspec(dllexport) int func() {
   return 3;
}

The following example creates a pure client that consumes the native function. However, the calling convention under /clr:pure is __clrcall. The following example generates LNK2028.

// LNK2028_b.cpp
// compile with: /clr:pure lnk2028.lib
// LNK2028 expected
int func();

int main() {
   return func();
}
