"List all references in the solution by Project and show the actual Reference used.
Sometimes Visual Studio will show an assembly reference path incorrectly when inspecting the properties. Example: the reference path might show /projecta/bin when in actual fact the path is ../packages/something. Also if Visual Studio is unable to find an assembly reference it will display the path as "".
Accurate References will parse the Solution and it's Project to show you the actual assembly path.

Here's some snaps of this extension, using libemgucv-windows-x86-gpu-22.214.171.1247.zip as the Solution.
Note the red references? There's a hint on the Project on which one to load, but another is being loaded instead.
I don't have mono on this system, VS is fixing up the references auto-magically and the extension is letting me know that... That's pretty cool.
