Configuring managed code that runs via COM interop

Scenario: .Net managed code library (assembly) depends on settings in a .config file. The library is used via COM interop from some unmanaged code application (i.e. MyLegacyGame.exe) written, say, in C++


Question: what should be the name of the .config file ?


Answer: MyLegacyGame.exe.config


There is a problem with that, however, if your native app is in fact part of windows
