I was wondering if Resharper makes any interfaces available to Visual Studio extensions via MEF. I want to write a VS extension that will access additional information from the Resharper Model if it is available but function perfectly well without having Resharper installed.
One simple example of this would be an text adornment extension that rendered .net code comments inline with the code. If Resharper is installed and active, the extension would be able to provide different (more intelligent) behaviours when clicking on or hovering over items (e.g. clicking on a class could invoke R# Navigate To menu)
