Laurent, Ah, I'd used @executable_path in a dll.config, it hadn't occurred to me that it could also be passed to DllImportAttribute.
If I switch my DllImport parameter to use @executable_path/../..., I can successfully call the unmanaged methods when running my application as a standalone app bundle, however, it no longer works when running from a non-standalone app build. If I can use the same string for both configurations, that would obviously be ideal. As it is now, I'll probably set up a try/catch fallback so that I can operate in both configurations.
