When I'm in a project that has references to libraries in the Dependencies folder, I occasionally need to check the version of the libraries I've referenced. My tool, FileVersion, takes two parameters, a start directory and a search directory, and walks up the start directory one level at a time until it finds the search directory. It then reports on the versions of the libraries (.dll and .exe) in that directory.
If the tool is called as an external tool in Visual Studio, it can be configured to search for the dependencies for the current project.
The output from running the tool looks like this in VS, saving you traversing the directory structure yourself and viewing each file's properties manually
