Annotations for unowned code, configured in code

Is there anyway that annotations can be configured using code directly (as opposed to the xml files)? I'd really like to define it in code so i'm not tied to the file location of the DLL since the DLL is delivered via nuget packages, it doesn't really make sense to try to make an xml file follow it around.

Also it would eliminate my exact version dependence the way the configuration wants you to specify the full assembly name. All of that would just be correct if I configured it via code.
