As I understand it, there are ways. A StackOverflow question pointed me to some code [lifted from the Galio project](http://apichange.codeplex.com/SourceControl/changeset/view/76c98b8c7311#ApiChange.Api/src/Introspection/CorFlagsReader.cs). I've not tried it.

For one of the projects I work on at the Day Job, there are quite a few managed DLLs, and there'd be quite a lot of errors, and I worry that others may have the same experience. However, it's possible that mixed native/managed DLLs aren't a big problem in general, and I don't want to make a big deal over this if it's just my niche problem.
